Question

In which of the following steps does inversion occur?

A. Step 1
B. Step 2
C. Step 3
D. None

Answer 1

Correct Answer - `(a,c)`
In step 1. `(C-Br)` bond is broken to `(C-N_(3))` Hence, inversion occurs `(rarr0`.
In step 2, `(C-N= overset(o+)(N) = overset(o-)(N))` bond is not broken, So on inversion.
In step 3, `(C-Br)` bond is broken to `(C-OH)` bond, hence, inversion occures `(rarr)`
