Question

Use the figure below to answer the question that follows.
Which of the four molecular structures. I-IV, exhibits trigonal planar molecular geometry?

• A. I
• B. II
• C. III
• D. IV

Answer 1

The correct option is A I

Trigonal planar is a molecular geometry model with one atom at the center and three atoms at the corners of an equilateral triangle, called peripheral atoms, all in one plane.

One lone and three bond completes the octet of the central atom.
