The compound which on reaction with aqueous HNO2 at low temperature produces an oily nitrosoamine is
methyl amine
ethyl amine
diethyl amine
aniline
Amongst the following the most basic compund is
benzyl amine
aniline
acetanilide
p -nitroaniline
A.
benzyl amine
As -NH2 group is directly attached to the benzene ring, so basic character of compound decreases because lone pair electrons present on nitrogen takes part in resonance, hence these are not free for donation. Decreasing order of basic nature is as follows Benzyl amine > acetanilide > aniline >p-nitroaniline.
Polymerisation in which two or more chemically different monomers take part, is called
