Answer 2

The Answer is option d:

Explanation:

• The correct answer is option (d) HCl.

• Shared pairs or bonding pairs are the stable balance of attractive and repulsive forces between atoms when they share electrons,
• while covalent bonding is the stable balance of attractive and repulsive forces between atoms when they share electrons.
• There are 3 types of covalent bonds:
• singular, double and triple bonds
• When two electrons are shared, a single bond is formed, which is made up of one sigma bond between the two atoms.
