Question

identify the molecular geometry around the nitrogen atom highlighted red in the given organic molecule. select one: linear trigonal pyramidal tetrahedral trigonal planar

Explanation:

Step1: Determine electron - pair geometry

The nitrogen atom has 3 bonding pairs (to 3 hydrogen atoms) and 1 lone pair. The total number of electron - pairs around the nitrogen atom is 4. According to VSEPR (Valence - Shell Electron - Pair Repulsion) theory, the electron - pair geometry for 4 electron - pairs is tetrahedral.

Step2: Determine molecular geometry

The presence of a lone pair affects the molecular geometry. When there are 3 bonding pairs and 1 lone pair around a central atom, the molecular geometry is trigonal pyramidal.

Answer:

Trigonal pyramidal
