MCQ

$IUPAC$ name of $C{H_3} - \mathop {\mathop {CH - C{H_2}}\limits_{|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} }\limits_{C{H_3}\,\,\,\,\,\,\,\,\,\,\,} - CH = C{H_2}$ is

A
$2-$ methyl pentene
✓
$4-$ methyl pentene $-1$
C
$1-$ hexene
D
$2-$ methyl pentene $-1$

✓

Answer

Correct option: B.

$4-$ methyl pentene $-1$

b
since it contains double bond hence it is alkene and it also has methyl group attached to the fourth carbon atom, Thus its IUPAC name of the compound will be:
