Which molecular geometry is least likely to result from a trigonal bipyramidal electron geometry?

A.Trigonal planar✓ Correct

B.See-saw

C.Linear

D.T-shaped

Explanation

Trigonal bipyramidal → electron pair = 5(5BP+OLP) See-saw → electron pair = 5(4BP+1LP) T-shape → electron pair = 5(3BP+2LP) Triganal planar → electron pair = 3(3BP) Linear → electron pair = 5(LP=3, BP=2)
