Chapter 8: Q57P (page 369)

What orbitals contain the electrons represented as lone pairs in the structures of quinoline, indole, imidazole, purine, and pyrimidine?

Short Answer

Expert verified

a) Nitrogen is attached with carbon with a single bond hence it is sp3hybridized.

b) Nitrogen is attached with carbon with a double bond hence it is sp2hybridized.

c) Nitrogen is attached with carbon with a triple bond hence it is sphybridized.

Step by step solution

01
