The IUPAC name of the following compound is?

Question -

The IUPAC name of the following compound is?

Options:

A . 5, 5-(1,1-Dimethylpropyl)-2-methyldecane

B . 5, 5-Bis(1,1-dimethylpropyl)-2-methyldecane

C . 5, 5-Bis(1,1-dipropylmethyl)-2-methyldecane

D . None of these

Answer: Option B
:
B

Decide the parent chain and give the numbering so that more substituted substituent will get the least number.

parent chain

10 carbons $\Rightarrow$ word root $\Rightarrow$ dec

single bond $\Rightarrow$ suffix $\Rightarrow$ ane

substituents at $C_{5} a n d C_{2}$

Now,

There is one more same substituent on $C_{5}$

Therefore,

5,5-Bis-(1,1-dimethyl propyl)

Bis $\Rightarrow$ Because two same substituents are there, and a methyl group at $C_{2} \Rightarrow$ 2-methyl

Therefore,

5,5-Bis-(1,1-dimethylpropyl)-2-methyldecane
