Quinoline is a heterocyclic amine.


The hybrid orbital that characterizes and differentiates alkynes from other simple hydrocarbons like alkanes and alkenes, is that alkynes have hybrid orbitals which have:

A 75% p character and 25% s character
B 66% p character and 33% s character
C 50% p character and 50% s character
D None of the above
Ans. C Alkynes are characterized by hybrid orbitals called sp orbitals. In the sp orbitals, there is 50% s character and 50% p character.
