Question

What is the IUPAC name for the following binary molecule? ClCH2CH2CH2CHCl2?

Answer 1

Cl--CH2--CH2--CH2--CH=Cl2

as no double or triple bond name will end with -ane

as there are 4 carbon atoms root word is But

hence butene

as there are 3 chlorine atoms prefix is TriChloro

Now numbering

as the chlorine atoms are on end numbering is

1,1,4

HENCE IUPAC name IS

"1,1,4 - TriChloroButAne"

Answer 2

1,1,4-trichlorobutane

Answer 3

1-4-dichloro-butene

Answer 4

This is how it looks like:

Cl -- CH2 -- CH2 -- CH2 -- CH -- Cl2

All single bonds, so name ends with -ane.

There are 4 carbons, so the name ends with butane.

The first carbon is the one wherein Cl2 is attached (it has higher priority than the one wherein only one Cl is attached).

The first carbon is designated with 1. There are two chlorine, so you have 1-dichloro-

The fourth carbon is designated with 4. There is one chlorine, so you have 4-chloro-

The full name is 1-dichloro-4-chlorobutane

Edit: om s got it :)
