Q. The IUPAC name of
$(C H_{3})_{3} C - C H = C H_{2}$ is

3,3-dimethyl-l-butene

2,2-dimethyl-3-butene

1,1,1-trimethyl-2-propene

3,3,3-trimethyl-2-propene

This compound contains double bond, so the end of the longest chain which is near the double bond will be given number $1$ .
This compound also contain side chain but preference will be given to double bond.
Therefore, the IUPAC name of the compound is
$3, 3$ -dimethyl- $1$ -butene.
