Front

What is the significance of the octet rule in molecular geometry?

Back

The octet rule helps predict the arrangement of electrons around an atom, influencing molecular shape.

Front

How does the presence of lone pairs affect molecular geometry?

Back

Lone pairs can repel bonding pairs, altering bond angles and the overall shape of the molecule.
