Answer 2

In the reaction given below ‘Z' is :

Reaction :

HCONHR + POCl3 → Z + H2O

• This reaction is the reaction which dehydrate amides into nitrile.

• The amide reacts with POCl3 to form an intermediate that removes chloride ion.

• Followed by deprotonation at intermediate.

• At last, elimination of reactive intermediate gives

• HCONHR + POCl3 → R-NC + PClO2 + H2O

• Hence Z is R-NC
