Question

drag each label to the correct location. identify the molecular shape of each lewis structure. bent tetrahedral trigonal planar trigonal pyramidal reset next

Explanation:

Step1: Analyze first structure

The central - nitrogen atom in $\text{NI}_3$ has 3 bonding pairs and 1 lone pair. According to VSEPR theory, the molecular shape is trigonal pyramidal.

Step2: Analyze second structure

The central - carbon atom in $\text{CCl}_4$ has 4 bonding pairs and 0 lone pairs. According to VSEPR theory, the molecular shape is tetrahedral.

Step3: Analyze third structure

The central - boron atom in $\text{BF}_3$ has 3 bonding pairs and 0 lone pairs. According to VSEPR theory, the molecular shape is trigonal planar.

Step4: Analyze fourth structure

The central - nitrogen atom in $\text{NO}_2^-$ has 2 bonding pairs and 1 lone pair. According to VSEPR theory, the molecular shape is bent.

Answer:

trigonal pyramidal, tetrahedral, trigonal planar, bent
