Vedclass · Answer

(C) The reaction of nitroalkanes with nitrous acid $(HNO_2)$ is used to distinguish between primary,secondary,and tertiary nitroalkanes.Primary nitroalkanes $(R-CH_2-NO_2)$ react with $HNO_2$ to form nitrolic acids,which dissolve in $NaOH$ to give a red color.Secondary nitroalkanes $(R_2CH-NO_2)$ react with $HNO_2$ to form pseudonitroles,which are blue in color.Tertiary nitroalkanes do not react with $HNO_2$.The compound $CH_3-C(NO)(NO_2)-CH_3$ is a pseudonitrole,which exhibits a blue color.

Which one of the following compounds gives a blue color when treated with nitrous acid $(HNO_2)$?
