Nomenclature of Covalent Compounds

Question 8 • *26-27 CFISD TX-Chemistry A CR

Choose the name of the molecular geometry for each molecule described below. A molecule with two atoms and no lone pairs around the central atom has a shape.

Answer
A
linear
B
trigonal-bipyramidal
C
tetrahedral
D
bent

Explanation

A molecule with two atoms has the atoms arranged along a single line, so its molecular geometry is linear. With no lone pairs around the central atom, there are no lone-pair effects that would change the shape. The correct choice is linear.
