Question
Which molecule has a bond angle of approximately 102° due to lone pair repulsion?
Explanation
In NF₃, nitrogen is sp³ hybridized with 4 electron pairs (3 bonding, 1 lone), forming a trigonal pyramidal shape. The F-N-F bond angle is ~102°, reduced from 107° in NH₃ due to greater lone pair repulsion from electronegative fluorine atoms.
