Which one of the following will react with acetamide to give methyl amine?
PCl5
NaOH + Br2
Soda lime
H2SO4
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.
Acetylene reacting with HCN in presence of Ba(CN)2 gives
vinyl cyanide
1,1-dicyanoethane
1,2-dicyanoethane
None of the above
In dehydrolysing reaction, CH3CONH2 CH3CN + H2O the hybridisation state of carbon is changed from
sp3 to sp2
sp to sp2
sp2 to sp
sp to sp3
RCONH2 + Br2 + KOH → Amine
This reaction is
Carbyl amine reaction
Mustard oil reaction
Hofmann bromamde reaction
Cannizaro reaction
