`R- NO_(2) overset(HNO_(2))rarr X overset(NaOH)rarr` Blue colour in above reaction R is

A

`CH_(3)-`

B

`CH_(3)CH_(2)-`

C

`CH_(3)CH_(2)CH_(2)-`

D

`CH_(3)- underset(underset(CH_(3))(|))(C)H-`

Text Solution

Verified by Experts

The correct Answer is:
D
`CH_(3)- underset(underset(CH_(3))(|))overset(overset(NO_(2))(|))(CH) + HO- N= O rarr CH_(3)- underset(underset(CH_(3))(|))overset(overset(NO_(2))(|))(C)- NO` Pseudonitro `overset(NaOH)rarr` Blue Colour
Secondary nitroalkane yield pseudonitrol which dissolved in alkali to give blue colour solution.
