Which of the following reactions is correct?

Answer»

a.
b.
C.
d.

Solution :`ROH` (aliphatic alcohol) on reaction with `(HNO_(3)+H_(2)SO_(4))` gives `R-O-NO_(2)`. So `(a)` is incorrect and `(b)` is correct.
c. `LAH` REDUCES `(-CHO)` group to alcohol without affecting the `(C=C)` bond.
So, the statement `(c )` is WRONG.
d. ETHERS are obtained (Williamson synthesis) when `1^(@) RX` reacts with `3^(@)` alkoxide. In the problem, `3^(@) RX` reacts with `1^(@)` alkoxide. So alkene will be obtained. So, the statement `(d)` is wrong, and consequently the answer is `(b)`.
