Question

Triethylamine [(CH3CH2)3N] is a molecule in which the nitrogen atom is hybridized and the CNC bond angle is .
Options
A sp2; >109.5°
B sp2; <109.5°
C sp3; >109.5°
D sp3; <109.5°
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

The nitrogen in triethylamine is sp3 hybridized with a trigonal pyramidal geometry. The C-N-C bond angle is less than 109.5° (about 108°) due to the lone pair on nitrogen, which occupies more space and compresses the bond angles.

Hint

What is the hybridization and geometry of nitrogen in amines?
