(a) Interpretation: The H − C = O bond angle in methyl formate is to be predicted. Concept introduction: VSEPR theory is an important model that is frequently used in chemistry to decide the shape and geometry of the molecules. VSEPR model is the extension of Lewis model. As the Lewis model is not able to explain the shape of the molecules. The shape in VSEPR model gives specific angles between the bonds for the corresponding shape and these angles are known as bond angles.

(b)

Interpretation:

The two structures of methyl formate: one in which the dihedral angle is 0° and the other in which it is 180° have to be drawn.

Concept introduction:

The angle between the two intersecting planes is known as dihedral angle. It is also described as the angle between the planes passing through two sets of three atoms. There should be two atoms in common. It is also known as the torsion angle.
