Which molecule has a non-linear shape (i.e.,for which molecule are the nuclei not in a straight line)?
A)O=C=O
B)H-O-H
C)H-Cl
D)H-C$\equiv$N
E)H-C$\equiv$C-H

Question

Quizplus · Accepted Answer

The molecule H-O-H (water) has a non-linear shape due to the presence of two lone pairs of electrons on the oxygen atom, causing repulsion and forcing the hydrogens to be bent at an angle. The other molecules (A, C, D, and E) all have linear shapes with the nuclei in a straight line.
