What is the molecular geometry around an atom in a molecule or ion which is surrounded by one lone pair of electrons and four single bonds.
A)see-saw or distorted tetrahedron
B)trigonal bipyramidal
C)linear
D)T-shaped
E)trigonal planar

Question

Quizplus · Accepted Answer

The presence of one lone pair and four single bonds indicates a total of five electron pairs around the central atom. This corresponds to a trigonal bipyramidal shape, but since one of the positions is occupied by a lone pair, the shape becomes distorted and is known as see-saw or distorted tetrahedron.
