Question

Nitrogen atom of amino group is _______hybridised.

• A. $sp$
• B. $sp^2$
• C. $sp^3$
• D. $sp^3\,d$

Answer 1

Answer: (C)

$sp^3$

Answer 2

The nitrogen atom of the amino group is usually $s p^{3}$ hybridised. As the atomic number of nitrogen is 7 , the valence shell has 5 electrons i.e $2 s^{2} 2 p^{3}(1 s$ and $3 p$ orbitals are participating in hybridization). one pair of electron acts as a lone pair and the remaining three electrons forms bonds with either hydrogens or alkyl or aryl groups. Nitrogen also shows $sp^{2}$ hybridization, where there are only 2 bonds are formed, one among them forming a partial double bond or a double bond.
