Question

1. Which among the following compounds undergo SN substitution easily – 3° or 1° alkyl halide? Give reason. Justify.

2. Grignard reagents should be prepared under anhydrous conditions. Give reason.

Answer 1

1. 3°- alkyl halide. Because the 3° carbocation is more stable than a 1° carbocation.

2. Grignard reagents react with water and get decomposed (hydrolysed). Hence they should be prepared under anhydrous conditions.
