(a)
Interpretation:
The shape of the given compound is needed to be predicted.
Concept introduction:
Molecular shape can be predicted from the Lewis structure by using the valence-shell Electron-pair repulsion (VSEPR) model.
-Count the number of valence electron pairs (bond pairs and lone pairs).
-Assume that the valence electron pairs form a structure that allows them to be as far away from each other as possible.
-If there are only two bond pair electrons, the molecule is linear.
-If there are three bond pair electrons, the molecule is shaped like a trigonal planar.
-If there are four bond pair electrons, the molecule is shaped as a regular tetrahedral.
- Repulsion between lone pair-bond pair of electrons effect the geometry of molecules.

- In principle, there are many different, chemically diverse ways in which small molecules can be linked to form polymers. For example, the small molecule ethene (CH2=CH2) is used commercially to make the plastic polyethylene (...–CH2–CH2– CH2–CH2–CH2–...). The individual subunits of the three major classes of biological macromolecules, however, are all linked by similar reaction mechanisms, i.e., by condensation reactions that eliminate water.
