MCQ
The structure of $4-$ methyl pentene $-2$  is
  • A
    ${(C{H_3})_2}CH - C{H_2}CH = C{H_2}$
  • ${(C{H_3})_2}CH - CH = CH - C{H_3}$
  • C
    ${(C{H_3})_2}CH - C{H_2}CH = CH - C{H_3}$
  • D
    ${(C{H_3})_2}C = CHC{H_2}C{H_3}$

Answer

Correct option: B.
${(C{H_3})_2}CH - CH = CH - C{H_3}$
b
The structure of $4$ -methyl pent-$2$-ene is $\left( CH _3\right)_2 CH - CH = CH - CH _3$.

$\left( CH _3\right)_2 CH - CH _2 CH = CH _2$ is named as $4$-methyl pent-$1$-ene.

$\left( CH _3\right)_2 CH - CH _2- CH = CH - CH _3$ is named as $5$-methyl hex-$2$-ene.

$\left( CH _3\right)_2 C = CH - CH _2- CH _3$ is named as $4$-methyl pent-$3$-ene.
