Question

does these have reasonance SiO3^-2 ,B2CI4 , HNO2 ,SF2 ,HCO3^-1 ,COS ,N2CIBr3 , CH2CI2 , HBO3^-2 ,SES2 ,CH3COCN AND WHAT IS THE SHAPE (MOLECULAR GEOMETRY NAME ) AND THE DEGREE (BOND ANGLE)

Answer #1

**Part a**

has the following resonance structures.

The molecular geometry is trigonal planar. The O-Si-O bond angle is 120 degrees.

**Part b**

doesn't show resonance. The structure of the molecule is as follows.

The geometry around one B atom is trigonal planar. The Cl-B-Cl and Cl-B-B bond angle is 120 degrees.

**Part c**

has the following resonance structures.

The molecular geometry around N is bent/ angular. The bond angle is 111 degrees.

**Part d**

has the following geometry. It doesn't show resonance.

The molecular geometry is bent/ angular. The bond angle is close to 109.5 degrees.
