What is the O-N-O bond angle in NO₃^-? A)less than 109.5° B)109.5° C)120° D)greater than 120°

Question

Quizplus · Accepted Answer

The molecule given contains three atoms of sulfur and one atom of phosphorus. All these atoms have a non-bonding pair of electrons on them. Due to this, they will repel the bonded pairs of electrons, which will distort the bond angles from the ideal values.

The molecule has a planar structure, and the O-N-O bond angle should be close to 120° due to the influence of the three sulfur atoms and one phosphorus atom. Therefore, the correct answer is (C) 120°.
