Molecular Geometry

Question 3 • *26-27 CFISD TX-Chemistry A CR

A molecule has two atoms that are bonded to the central atom and one lone pair of electrons around this central atom. What is the shape of the molecule?

Answer
b
bent
l
linear
t
trigonal planar
t
trigonal pyramidal

Explanation

The central atom has three regions of electron density: two bonds and one lone pair. These arrange in a trigonal planar electron geometry, but the molecular shape describes only the atoms. With one lone pair taking the third position, the two bonded atoms form a bent shape.
