How to judge the chemical formula is a primary halide alkane

To be added to the carbon atom originally had several alkyl groups to judge, the number, corresponding.

Uncle face even four bonds full c secondary hydrogen boe.

Identification: andSilver nitrateto see how fast or slow the rate of precipitate formation is.

Reaction rate. The tertiary halogen type is greater than the secondary and the primary is greater than the ethylene type, and the tertiary halogenated hydrocarbon.

Precipitates are formed within a few minutes, secondary halogenated hydrocarbons need to be warmed, primary halogenated hydrocarbons are slower, ethylene or benzene halogenated hydrocarbons cannot react with silver nitrate, and no precipitation is formed even if heated.

Halogenated hydrocarbons. Hydrogen atom in a hydrocarbon molecule.

Compounds that are replaced by halogen atoms are called halogenated hydrocarbons, or halocarbons for short. The general formula of halogenated hydrocarbons is: (ar)r-x, where x is the halogen atom, which can be regarded as the functional group of halogenated hydrocarbons.

Including fluorine, chlorine, bromine, iodine.

According to the different halogens, they are called fluorobenzohydrocarbons, chlorinated hydrocarbons, brominated hydrocarbons and iodine hydrocarbons, and can also be divided into monohalogenated hydrocarbons, dihalogenated hydrocarbons and polyhalogenated hydrocarbons according to the number of halogen atoms in the molecule, and can also be based on the hydrocarbon group.

It is divided into saturated halogenated hydrocarbons, unsaturated halogenated hydrocarbons and aromatic halogenated hydrocarbons.

Primary halide alkanes are written as:c-x（x=cl，br，i）。

Halogenated hydrocarbons. The name is given to the corresponding hydrocarbon as the parent and the halide atom as the substituent. If there is a carbon chain substituent, the carbon chain should be written in front of the halogen atom according to the sequential rules; If there are multiple halogen atoms, the order listed is fluorine, chlorine, bromine, iodine.

C-F bonds generally have considerable stability and react with other halogens.

Different, hydrolysis: coheating with an aqueous solution of a strong base, the halogen atom is replaced by a hydroxyl group (-OH) to form an alcohol.

For example: ch3ch2ch2cl 1-chloropropane (1°) resonant.

According to the number of halogen atoms, it is divided into one haloalkane, dihaloalkane, and polyhaloalkane.

According to the different types of sakura halide atoms, it is divided into fluoroalkane, chlorinated alkane, bromoalkane, and iodoalkane.

According to the different alkyl groups, it is divided into saturated halide alkanes, unsaturated halide alkanes, and halogenated aromatic hydrocarbons.

Christen. Select the main chain first, then number it, and finally add the parent name and substituent name, and write the correct full name of the mess.

Halogen. atoms and alkyl groups.

When the excitation of the oak group is used, which is closest to the end of the chain, it is numbered from which end; When the distance from the end of the chain is equal, it is numbered from the end closest to the halogen atom. When writing, write the alkyl group first, and then the halogen atom.

When there is a double bond, it is unknown which of the side tube double bond and the halogen atom is closer to the end of the chain, and it is numbered from the end closest to the double bond.

If you want to identify halogenated hydrocarbons as grade 1 halogenated hydrocarbons or grade 2 or grade 3, such as chlorobutane, 1-methylchloropropane, and tert-butyl chloride, the three are isomers, but they belong to grade halogenated hydrocarbons.

The identification method is to react with the alcohol solution of silver nitrate.

The rate is 3 grade benzyl halogen type 2 grade 1 ethylene type benzene type.

Level 3 spawns in a matter of minutes, Level 2 needs to be warm, and Level 1 is even slower. The ethylene type does not react with the benzene type, and no precipitation is formed even when heated.
