Tardigrade Admin · Accepted Answer

The - OH group of alcohol or the - COOH group of a carboxylic acid is replaced by - Cl using phosphorus penta chloride (ie, PCl 5 ) underset text Alcohol ROH + PCl 5 longrightarrow RCl + POCl 3+ HCl underset textAcidRCOOH+ PCl 5 longrightarrow RCOCl + POCl 3+ HCl

Q. The $- O H$ group of an alcohol or the $- COO H$ group of a carboxylic acid can be replaced by $- Cl$ using

phosphorus pentachloride

hypochlorous acid

chlorine

hydrochloric acid

The $- O H$ group of alcohol or the $- COO H$ group of a carboxylic acid is replaced by $- Cl$ using phosphorus penta chloride (ie, $PC l_{5}$ )
$Alcohol RO H + PC l_{5} ⟶ RCl + POC l_{3} + H Cl$
$Acid RCOO H + PC l_{5} ⟶ RCOCl + POC l_{3} + H Cl < b r / >$

Q. The −OH group of an alcohol or the −COOH group of a carboxylic acid can be replaced by −Cl using
