Q20 / 54 · KVPY 2017 (5 Nov SA) · Chemistry

The reaction of an alkene $X$ with bromine produce a compound $Y$, which has $22.22 \%$ C, $3.71 \% \mathrm{H}$ and $74.07 \%$ Br. The ozonolysis of alkene $X$ gives only one product. The alkene $X$ is : [Given: atomic mass of $c=12 ; H=1 ; B r=80]$

  • A
    ethylene
  • B
    1 -butene
  • Correct answer
    C
    2 -butene
  • D
    3-hexene

Solution

From the data given, $\mathrm{X}$ will be $\mathrm{CH}_{3}-\mathrm{CH}=\mathrm{CH}-\mathrm{Ch}_{3}$ which on ozonolysis gives ethanal.

Hence, the correct answer is option: 'C'.
