Medium MCQ +4 / -1 PYQ · JEE Mains 2021

Given below are two statements :

Statement I : C2H5OH and AgCN both can generate nucleophile.

Statement II : KCN and AgCN both will generate nitrile nucleophile with all reaction conditions.

Choose the most appropriate option :

  1. A Statement I is false but statement II is true.
  2. B Both statement I and statement II are true.
  3. C Both statement I and statement II are false.
  4. D Statement I is true but statement II is false. Correct answer

Solution

Both C<sub>2</sub>H<sub>5</sub>OH and AgCN can generate nucleophile.<br><br> KCN generates nitriles on substitution reactions with haloalkanes where AgCN generates isonitriles on substitution reactions with haloalkanes. Because KCN is ionic and has ‘C’ nucleophilic centre whereas AgCN is covalent and has ‘N’ nucleophilic centre.
