What is CH30H and what is ch3oh?

Whether a substance is ionic or polar molecule, non-polar molecule, is seen by the subtraction of their respective electronegativity"This is absolutely imperfect. Diatomic molecules can be judged using this rule.

CaCl2 is ionic, which is a matter of judging the type of chemical bond of a substance, not judging the polarity or non-polarity. Moreover, the concept of polarity only makes sense in molecules, while CaCl2 is an ionic compound.

In CH3OH, it is impossible for the 2 C-H to be symmetrical. The central c atom is sp3 hybridized and has a tetrahedral configuration, so it is impossible to find two c-hs in the same straight line. To calculate the polarity of this molecule, it should be calculated using the method of vector synthesis.

Methanol is liquid at room temperature and pressure.

N20 is not what you wrote. See image below!

This molecule cannot be explained by the valence bond theory, and the bonding situation is more complicated. Among them is the Off-Origin Party key.

OH is a hydroxyl group, and there is only one carbon atom in the compound, so it is called methanol, which is the main component of industrial alcohol, which has strong liver toxicity and eye toxicity, and has a relatively low boiling point. More can be found in the encyclopedia for "methanol".

It can't be subtracted directly, it should be vector subtraction.

2 c-h cannot cancel each other, 3 c h and -oh are tetrahedral structures, and the vectors are subtracted.

Methanol is in liquid form.

The n20 structure is n-n-o

Common keys are more difficult to express, look at the picture.

CH3OH is methanol.

Methanol is also known as hydroxymethane.

It is an organic compound and is toxic. It is the saturated monool with the simplest structure. Its chemical formula is CH3OH CHO, where CHOH is a simple structural formula, which can highlight the hydroxyl group of methanol, the CAS number is 67-56-1, the molecular weight is, and the boiling point is.

Because it was first discovered in dry distilled wood, it is also called "wood alcohol." or "wood spirits."

Applications of methanol:

1. The main application field of methanol is the production of formaldehyde, which can be used to produce adhesives, mainly used in the wood processing industry, followed by the treatment agent for molding compounds, coatings, textiles and paper.

2. Another main use of methanol is the production of acetic acid. Acetic acid consumes about 7% of global methanol demand and produces vinyl acetate, acetate fibers and acetate, among others, which are closely related to the demand for coatings, adhesives and textiles.

3. Methanol can be used to make methyl formate, and methyl formate can be used to produce formic acid and formamide.

and other fine chemical products, it can also be used as insecticides, fungicides, fumigants, tobacco treatment agents and gasoline additives.

4. Methanol can also make methylamine, which is an important aliphatic amine with liquid nitrogen.

and methanol as raw material, which can be separated into monomethylamine by processing.

Dimethylamine, trimethylamine, is one of the basic chemical raw materials.

It should be methanol (CH3OH).

It is impossible to have 30 hydrogen atoms on a carbon atom, probably by losing o to 0.
