The molecular structure of P4O6 contains only single bonds, then the number of covalent bonds contai

The molecular structure of P4O6 contains only single bonds, so the number of covalent bonds is 12.

Phosphorus oxide is a dimerized molecule P4O6 in either gaseous or liquid state, in which 4 phosphorus atoms constitute a tetrahedron, and 6 oxygen atoms are located on the outside of each edge of the tetrahedron, forming a P-O single bond with two phosphorus atoms respectively, and each phosphorus atom is connected with 3 surrounding oxygen atoms with O-P bonds to form a tetrahedron. Three of the oxygen atoms are shared with the other three tetrahedra. The P-O bond length is 165pm, the bond angle POP is 128 degrees, and the OPO is 99 degrees.

Phosphorus trioxide (chemical formula: P4O6) is a compound composed of oxygen and phosphorus, which is a colorless waxy extremely toxic crystal with the smell of garlic, although its correct name should be phosphorus hexoxide, but it has been thought that the molecular structure is P2O3, so the name phosphorus trioxide has been used to this day.

Space can only be imagined.

The 4 P's make up a regular tetrahedron. Note: At this point p already satisfies the 8-electron structure.

The regular tetrahedron has 6 edges.

Then you insert the o in the middle of each of the 6 edges, so that the o is also satisfied.

In this way, it is clear that there are 2 bonds next to each oxygen, for a total of 12 covalent bonds.

For example, p, the outermost number of electrons is 5, and to satisfy the 8 electronic structure, 3 electrons are required.

o The outermost number of electrons is 6, and 2 electrons are required to satisfy the 8 electronic structure.

p4o6 four p six o (4 times 3 + 2 times 6) divided by 2 to give answer 12

It's easy. P4O6, oxygen negative bivalent, 6*2=12

You use this method to try CO2,CH4 is done.。。 Just look at the positive or negative. Multiply the valency by the number of atoms + the number of chemical bonds that do not show valency.

For example, n-butane, there are three C-C bonds, and the electronegativity of C-C is the same, so it does not exhibit valency, C4H10, 10*1+3=13

First of all, we must judge his molecular structure.

From the inscription, it can be seen that the 4 p atoms are at the vertices of the regular tetrahedral form, and the o atoms are single bonds with the two p atoms at the vertices on the 4 edges of the regular tetrahedron.

In this way, it is clear that there are 12 covalent bonds in total.

There are a total of 12 covalent bonds, because in order to stabilize the structure into eight electrons, O should be bonded with two atoms, and P should be bonded with 3 atoms, exactly in P4O6, the atomic ratio is 2 to 3, indicating that P is only bonded with O, and O is also bonded only with P, and 6 O's, each with two bonds, 12 bonds.

The molecular structure of P4O6 is based on the P4 tetrahedron, with an O interpolated between each of the 6 P-Ps. Get 12 p-o

1. Generally, we start with p4 (white phosphorus.

According to the structural characteristics of the tetrahedron, there are 6 edges, that is, there are 6 p-p bonds. That is, every number of p's occupies 6 p-p in a molecule.

2. However, if the potato contains fruit, it forms covalent bonds with other compounds.

, P has +3 and +5 valences.

Summary. The ethane (C2H6) molecule consists of two carbon atoms and six hydrogen atoms, and its chemical formula is C2H6. Each carbon atom has 4 valence electrons and each hydrogen atom has 1 valence electron, so the ethane molecule has a total of (2 4) +6 1) = 14 valence electrons.

In the ethane molecule, a single bond is formed between two carbon atoms, and each carbon atom forms a single bond with three hydrogen atoms. Thus, there are a total of 7 covalent bonds in the ethane molecule.

A carbon-containing molecule contains 14 electrons and is a tetranuclear compound with only covalent bonds.

Hello dear, I found that the molecule containing carbon contains 14 electrons, which is a tetranuclear compound and only contains a covalent bond, and the molecule is ethane (C2H6).

The ethane (C2H6) molecule consists of two carbon atoms and six hydrogen atoms, and its chemical formula is C2H6. Each carbon atom has 4 valence electrons, and each hydrogen atom has 1 valence electron, so the ethane molecule has a total of (2 4) +6 1) = 14 valence electrons. In the ethane molecule, a single bond is formed between two carbon atoms, and each carbon atom forms a single bond with three hydrogen atoms.

Thus, there are a total of 7 covalent bonds in the ethyl-hypoalkane molecule.

Summary. Organic compounds with tetrahedral structure usually refer to methane molecules because the molecular structure of methane molecules is a tetrahedron.

Why is it said that in organic compounds with tetrahedral structure, there are six moles of carbon-carbon single bonds.

Organic compounds with tetrahedral structure usually refer to methane molecules because the molecular structure of methane molecules is a tetrahedron.

In the methane molecule, the carbon atom forms four covalent bonds with four hydrogen atoms, and these covalent bonds are all carbon-carbon friend. Since the methane molecule contains only one carbon atom, it can be said that there are six moles of carbon-carbon single bonds in organic compounds structured in tetrahedra (i.e., which of the six carbon-carbon single bonds is present in methane).

I'm sorry, but I don't really understand why there is a carbon-carbon bond of four moles and a carbon-carbon bond of six moles.

In this molecular structure, each carbon atom forms a single bond with three adjacent carbon atoms of the tremor, and their positions are equivalent, so that each carbon atom has six single bonds attached to the other carbon atoms. Therefore, the organic Xiaodongjian compound with a tetrahedral structure has a six-molar carbon-carbon single bond in it.

1. Generally speaking, from the structure of P4 (Changxiao white phosphorus), its shape is a regular tetrahedron, and 4 Ps occupy the four vertices of the regular tetrahedron, according to the structural characteristics of the regular tetrahedron, there are 6 edges, that is, there are 6 P-P bonds. That is, each p occupies 6 p-p in a molecule.

2. However, if it forms a covalent bond with other chemical resistance manuscript complexes, p has +3 and +5 valence.

Answer: B

The test point of this question is the application of ultraviolet spectroscopy in the determination of the structure of chemical components of traditional Chinese medicine. The principle of ultraviolet absorption spectroscopy (UV) is that electrons in a molecule can transition from the ground state to the excited state due to light irradiation. The absorption of chromophore molecules containing conjugated double bonds, chromophores, and conjugated systems in the ultraviolet and visible regions is corresponding

Jumps as well as n <

Therefore, ultraviolet spectroscopy is an important means for the structural identification of compounds containing conjugated double bonds, unsaturated carboxyl sensitive group structures and aromatic compounds in molecules.
