Question

which of the following will have a bent molecular geometry (not electron geometry) around oxygen as central atom? hint: you will have to try out lewis structures drawings before you can come up with correct answer) 1) h₂o 2) ch₃oh 3) f₂o 4) all of the above 5) only a and c

Explanation:

Step1: Determine Lewis structure of H₂O

Oxygen in H₂O has 6 valence - electrons. It forms 2 single bonds with 2 hydrogen atoms and has 2 lone - pairs. According to VSEPR theory, with 2 bonding pairs and 2 lone - pairs around oxygen, the molecular geometry is bent.

Step2: Determine Lewis structure of CH₃OH

In CH₃OH, the oxygen atom is bonded to a carbon atom and a hydrogen atom. Oxygen has 2 bonding pairs and 2 lone - pairs. According to VSEPR theory, the molecular geometry around oxygen is bent.

Step3: Determine Lewis structure of F₂O

Oxygen in F₂O has 6 valence - electrons. It forms 2 single bonds with 2 fluorine atoms and has 2 lone - pairs. According to VSEPR theory, with 2 bonding pairs and 2 lone - pairs around oxygen, the molecular geometry is bent.

Answer:

1. All of the above
