Options

A.
B.
C.
D.

Answer

D

Explanation

`1^(@)` nitro compound `2^(@)` nitro compound react with `HNO_(2)` acid but `3^(@)` nitro compound does not react with nitrous acid
(i) `CH_(3)- underset(underset(O)(||))(C)- underset(1^(@)"nitro")(overset(overset(CH_(3))(|))(CH)- NO_(2) overset(HNO_(2))rarr CH_(3)- underset(underset(O)(||))(C)- underset(underset(N= O)(||))overset(overset(CH_(3))(|))(C) - NO_(2)`
(ii) (ii) `CH_(3)- CH_(2)- CH_(2)- NO_(2) overset(HO- N= O)rarr CH_(3)- CH_(2)- underset(underset(N- OH)(||))(C)- NO_(2)`
`CH_(3) - underset(underset(CH_(3))(|))(CH)- underset(1^(@) "nitro")(CH_(2)- NO_(2) overset(HO- N= O)rarr CH_(3)- underset(underset(CH_(3))(|))(CH)- underset(underset(N- OH)(||))(C)- NO_(2) 3^(@) " nitro" overset(HNO_(2))rarr` No reaction.
