Question

how I can solve it?? plz guide me ​

Answer 1

Explanation:

Hydrogen bonds are strong intermolecular forces created when a hydrogen atom bonded to an electronegative atom approaches a nearby electronegative atom.

Greater electronegativity of the hydrogen bond acceptor will lead to an increase in hydrogen-bond strength.

HF H bonding is strongest. However, as water has two H atoms, each molecule can form two H bonds so on a per molecule basis, water H bonding is strongest (this is evidenced by the boiling points of the three substances; NH3 < HF < H2O.)

So option b is correct..

Answer 2

Explanation:

hydrogenhydrogen bonds are strong intermolecular forces created with hydrogen atoms bonded to an electronic approaches the nearby electric negative atom.

greater electronic activity of this hydrogen bond deceptive will lead to an increase in hydrogen bond strength.

HF h bonding is the strongest.however as water has to h8 which molecule conform to h wants one as per molecules which is water is wanting is strongest due to circumstances of boiling water.
