Which of the following statement(s) is/are correct?

Options

A.
B.
C. c.The compound `(A)` on reaction with `HI+Red P` gives

D. d.The compound `(A)` on oxidation with `MnO_(2)` gives

Answer

B, C

Explanation

During the elimination reaction, two eliminating group should be in anti-position, so less substituted alkene (Hofmann product) is formed.

So, statement `(a)` is wrong but `(b)` is correct.
c. `HI+P` reduces aldehyde to alkane, so the product is correct.
d. `MnO_(2)` oxidies selectively allylic or benzylic hydroxyl group. So `(A)` does not have any allylic or benzylic hydroxyl group. Hence, no reaction occurs. Thus, wrong product. So the answers are `(b)` and `(c )`.
