Among the following statements, the correct statement about and is:
(A) is a better electron donor because the lone pair of electron occupies a spherical s-orbital and is less directional
(B) is a better electron donor because the lone pair of electron occupies an -orbital and is more directionalCorrect
(C) is a better electron donor because the lone pair of electron occupies an -orbital and is more directional
(D) is a better electron donor because the lone pair of electron occupies a spherical s-orbital and is less directional
Answer: (B)
Solution
Nitrogen, being a small, second-period atom, shows effective s–p orbital mixing, so its lone pair resides in a well-directed hybrid orbital, allowing strong, directional overlap with an incoming proton/acceptor — making
