Possible Answers:

\(\displaystyle H_2O\) - Bent (v-shaped)

\(\displaystyle CCl_4\) - Tetrahedral

\(\displaystyle HCl\) - Linear

\(\displaystyle NH_{3}\) - Trigonal planar

\(\displaystyle CO_2\) - Linear

Correct answer:

\(\displaystyle NH_{3}\) - Trigonal planar

Explanation:

\(\displaystyle NH_3\) has three bonding pairs and one non-bonding pair, which is the geometry for trigonal pyramidal, not trigonal planar.
