Identify the major product ( P ) in the following reaction sequence. $\left(\mathrm{CH}_3\right)_3 \mathrm{CBr} \xrightarrow{\text { Alcoholic }} \mathrm{KOH} \Delta \xrightarrow{\mathrm{HBr}} \mathrm{P}$

• Correct answer
  A

  $\left(\mathrm{CH}_3\right)_3 \mathrm{CBr}$
• B

  $\left(\mathrm{CH}_3\right)_2 \mathrm{CHCH}_2 \mathrm{Br}$
• C

  
  
• D

  $\mathrm{CH}_3-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}_2 \mathrm{Br}$

Solution

$\left(\mathrm{CH}_3\right)_3 \mathrm{CBr} \xrightarrow[\mathrm{KOH} / \Delta]{\text { Alcoholic }} \mathrm{X} \xrightarrow{\mathrm{HBr}} \mathrm{P}$

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