Question

CH3-CH2-CH2Cl-CH-CH2OH-CH-(CH3)2

Answer 1

Answer:

1-chloro 2-ethyl 3-hydroxymethyl 4-methyl pentane.

Now come to rules:

Select longest carbon chain as parent chain keeping in mind that should contain most no. of locants(methyl,ethyl e.t.c).

Then we do numbering of carbon atoms according to this priority order.

Nearest locant > alphabetical order

If functional group is attached with carbon other than parent chain carbon then prefix for that functional group is used,so accordingly here for OH; hydroxy is used.
