Question

Write IUPAC name of (CH3)3 C CH2 CH2 CH(Br) CH3

Answer 1

can you tell me if these are all different

like this

(ch3)3-c-ch2-ch2

(CH3)3-C-CH2-CH2:

if we expand (CH3)3 it will be
CH3-CH3-CH3
Here 2 ch3 is bonded with one carbon of main chain so we will write di for two and methyl for ch3.
This compound have 5 carbons for which we use Pent and it is saturated carbon so it will be Pentane.
Answer will be : 2,2-dimethylpentane

ch2(br)-ch3 :
Br-CH2-CH3 :
as this have 2 carbons it will be of eth and it is saturated carbon for which we use ane - Ethane.
It have a Br for which we write Bromo
answer will be
1-Bromoethane
