polyhalogen compounds haloalkanes and haloarenes chemistry

  1. ${ CH } _{ 3 }{ CH } _{ 2 }{ CCl } _{ 3 }$

  2. ${ CH } _{ 3 }{ CCl } _{ 3 }$

  3. ${ CH }{ Cl } _{ 3 }$

  4. None of these

Show answer
Correct Option: B
Explanation:
Alkaline hydrolysis of a trichloro derivative will give a carboxylic acid. The carboxylic acid that gives red colouration with aqueous $FeCl _{3}$ is acetic acid $CH _{3}COOH$. Hence, the compound  A is $CH _{3}CCl _{3}$.
