MCQ
Ethylbenzene reacts with $\ce{Cl_2}$​ in sunlight to give :
  • $1-$ Chloro $-1-$ phenylethane
  • B
    $1-$ Chloro $-2-$ phenylethane
  • C
    $4-$ Chloroethylbenzene
  • D
    $3-$ Chloroethylbenzene

Answer

Correct option: A.
$1-$ Chloro $-1-$ phenylethane
$\mathrm{ph}-\mathrm{CH}_2 \mathrm{CH}_3+\mathrm{Cl}_2$​ $\xrightarrow{\text{sunlight}} \ \mathrm{ph}-\mathrm{CH}(\mathrm{Cl})-\mathrm{CH}_3$
This is a substitution reaction where chlorine replaces one hydrogen atom to form $1-$ chloro $-1-$ phenylethane.
