Question

Cyanohydrins can be synthesised from ketones through:

Options
  • A

    Nucleophilic addition reaction

  • B

    Unimolecular nucleophilic substitution reaction

  • C

    Electrophilic substitution reaction

  • D

    Bimolecular nucleophilic substitution reaction

  • E

    Nucleophilic elimination reaction

Explanation

A cyanohydrin reaction is an organic chemical reaction by an aldehyde or ketone with a cyanide anion or a nitrile to form a cyanohydrin. This is a base-catalysed nucleophilic addition reaction.

Cyanohydrins are organic compounds containing a carbon atom linked to both a cyanide group(-CN) and a hydroxyl group(-OH). Hydrogen cyanide adds to aldehydes or ketones to form cyanohydrins in a base-catalysed nucleophilic addition reaction.
