Mark the correct statement 
Methyl amine is a stronger base than
ammonia due to +I effect. The alkyl groups
which are electron releasing groups increase
the electron density around the nitrogen
thereby increasing the availability of the lone
pair of electrons to proton or lewis acid and
making the amine more basic
Indicate which nitrogen compound amongst thefollowing would undergo Hofmann reaction (i.e..,reaction with Br2 and strong KOH) to furnish theprimary amine (R – NH2) 
Only 1° amides (i.e. RCONH2) in the present case undergo Hoffmann bromamide reaction.

Any primary amine means both aliphatic as well as aromatic but onoalkylamines means only 1° aliphatic amines. Therefore, option (a) is correct while (d) is wrong.
What is the decreasing order of basicity of primary, secondary and tertiary ethylamines and NH3 ? 
In the solution phase, amines follow the reactivity as 2°>3°>1°>NH3, provided the alkyl group is not methyl.

Acetamide and ethylamine can be
distinguished by heating with NaOH
solution. Acetamide evolves NH3 but
ethylamine does not.

Which of the following reagents will convert pmethylbenzenediazoniumchloride into p-cresol? 
The consituent of the powerful explosive RDX is formed during the nitration of 
RDX is prepared by treating urotropine with fuming nitric acid. When the inner bridge system is destroyed by oxidation and the peripheral nitrogen atom are nitrated, it forms cyclonitrite (or RDX).
Which of the following is most basic in nature? 
(CH3)2NH is most basic because two electron releasing groups are present on Nitrogen. Also aromatic amines are less basic then aliphatic amines. The basic character of amines follow
R2NH > RNH2 > C6H5NHCH3 > NH3

The major organic product formed from the following reaction :
Electrolytic reduction of nitrobenzene in weaklyacidic medium gives 
Which of the following is more basic thananiline? 
Benzylamine is more basic than aniline. The reason is that in aniline, the lone pair of nitrogen is conjugated with benzene ring so it is not available readily for others. On the other hand in Benzylamine, nitrogen is not directly attached with ring so lone pairs are
not conjugated with ring.
Which one of the following on reduction withlithium aluminium hydride yields a secondaryamine? 
Reduction of alkyl isocyanides in presence of LiAlH4 yields secondary amines containing methyl as one of the alkyl group.
whereas, alkyl cyanides give 1° amine on reduction.
