Question

(CH3)2CHCH2C(CH3)3 iupac name?​

Answer 1

Answer:

1,1,5- trimethyl pentane

Explanation:

Prepare the chain by expanding the bracketed members, and take the longest possible length. In this case it forms 5.

CH3         CH3

/                 /

CH- CH2-C- CH3

/                 /

CH3          CH3

This will leave three methyl substituents. The naming must be done using the least sum rule, which means that the substituents must add up to the lowest possible number. Therefore, we start naming from the right instead of the left.

Hope it helps.
