Show Answer

Answer:

Correct Answer: 2. (d)

Solution:

  1. (CH3)3CCl gives a precipitate with AgNO3 solution because it forms stable carbocation. (i.e. tertiary) that readily combines with AgNO3 to give precipitates of AgCl.

CH2=CHCl forms unstable carbocation.

Hence, it does not readily react with AgNO3.
