RCI is hydrolysed to ROH slowly but the reaction is rapid if a catalytic amount of KI is added to the reaction mixture. Explain.

Text Solution

Verified by Experts

lodide is a powerful nucleophile and therefore, it reacts rapidly with RCI to form
`KI to K^(+)+I^(-)`

Further `I^(-)` ion is a better leaving group than `Cl^(-)` ion and therefore, RI is more readily hydrolysed to form

Knowledge Check

  • Assertion (A) : RCl is hydrolysed to ROH slowly but reaction is rapid if catalytic amounts of KI are added to the reaction mixture. Reaction (R ) : I^(-) is a powerful nucleophile which reacts rapidly with RCl to form RI. I^(-) is a batter leaving group than Cl^(-) and RI is hydrolysed rapidly to ROH.
