Does not show basic character because lone pair on nitrogen is delocalized by resonance with the carbonyl group which makes it less available for protonation
-$\underset{\text{(aliphatic primary amine)}}{{CH_{3}CH_{2}CH_{2}CH_{2} \overset{??{N}H_{2}}}$$R \to NH_{2}$
R-group due to $+1$ effect intensify the electron density on nitrogen. Therefore highly basic in nature.

$-NO_{2}$ group (-I) effect, therefore makes the ring electron deficient. Hence, acidic in nature
(neutral)
Nitrogen is the 7th element of the periodic table between carbon and oxygen.
It’s a crucial part of amino acids.
Around 80% of the Earth’s atmosphere comprises nitrogen gas.
It is odorless and colorless in nature, mostly diatomic non-metal gas.
Since it has 5 electrons in its outermost shell, most of its compounds are trivalent.
It is a combination of all living tissues. Since it is a component of DNA and part of a genetic code, it is a necessary element of life.
It is found in nitrates and further nitrites in soil and water.
The nitrogen cycle comprises all these substances and is interconnected. Industrial companies emit nitrogen enormously, increasing nitrite and nitrate content in the ground and water, being the repercussion of reactions in the nitrogen cycle.
