Hydrolysis of trichloromethane with aqueous KOH gives?
Aacetic acid
Bmethanol
Cformic acid
Correct Answer
Dethanol
Solution
Hydrolysis of trichloromethane with aqueous $$KOH$$-
$$CH{Cl}_{3} \xrightarrow[-3 HCl]{Aq. KOH} CH{\left( OH \right)}_{3} \xrightarrow[-{H}_{2}O]{} \underset{\left( \text{formic acid} \right)}{HCOOH}$$
Hence the hydrolysis of trichloromethane with aqueous $$KOH$$ gives formic acid $$\left( HCOOH \right)$$.
