Question

nomenclature of carbon compounds​

Answer 1

$\bold{HYDROCARBONS}$

The organic compounds which have hydrogen and carbon are known as hydrocarbons.

$\bold{NOMENCLATURE}$

Naming of organic compounds is known as nomenclature.

Nomenclature have two systems :-

◼Trivial system.

◼IUPAC system.

$\bold{TRIVAL \: SYSTEM}$

▶In this naming is done on basis of

✳Source of compound

✳Properties of compound

✳From latin or greek prefixes.

$\bold{IUPAC \: SYSTEM}$

◼LONGEST CHAIN RULE

The longest continuous chain of carbon is selected.

◼NUMBERING OF CARBON

▶Branched compund gets minimum number.

▶Alkyl group get minimum number.

▶Functional group gets minimum number.

▶When there are multiple functional group, they are named alphabetically.

▶When there are multiple alkyl groups alkyl , smallest alkyl gets minimum number.

▶Halo substance gets minimum number. Example :-Chlorine (Cl), Bromine (Br) etc.

▶Names of alkyl groups ard kept before parent hydrocarbons.

$CH_3 = Methyl$

$C_2H_5 = Ethyl$

Example :-

2- Methyl Butane

▶When there are multiple alkyl groups they are names as

Di = For 2

Tri = For 3

▶When two same alkyl groups are there on same carbon atom its written as:-

2,2 = For 2 alkyl groups on carbon at 2 place.
