Explain why water molecules form on average two hydrogen bonds per molecule, whereas ammonia molecules (NH3) form only one.

To form a Hydrogen bond, a hydrogen bond donor and a hydrogen bond acceptor are required. The hydrogen bond donors are lone pairs of electrons and hydrogen bond...

what is electronegativity and explain the trend in electronegativity as we go down the group?

The tendency of an atom to attract a shared pair of electrons towards itself is known as electronegativity. When we move from top to bottom in a group, ele...
