Predict the bond angles for the following molecules: (a) BeCl2, (b) BCl3, (c) CCl4, (d) CH3Cl, (e) Hg2Cl2 (arrangement of atoms: ClHgHgCl), (f) SnCl2, (g) H2O2, (h) SnH4.
(a)

Interpretation: The bond angle of the given molecule should be found.
Concept Introduction:
- Bond angle measured that made between two nearby bonds. The angles between two adjacent bonds are known as bond angle.
- Using VSEPR theory and Lewis structure, the exact geometry of a molecule can be obtained.
- In VSEPR, the geometry of the molecule is explained based on minimizing electrostatic repulsion between the molecules’ valence electrons around a central atom
- Lewis structures is also known as Lewis dot structures which represents the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
