Although the H-bonding in hydrogen fluoride is much stronger than that in water, yet water has a much higher boiling point than hydrogen fluoride.

Due to lowering in vapour pressure

(a) Working capital of a firm refers to the amount of current assets which are in excess over current liabilities. If a company has a higher working capital then there will...

Both the energy sources, coal and petroleum, take millions of years for their formation. As these resources are being utilised at a much faster rate than their formation, they will...

(i) It is due to (a) Intermolecular hydrogen bonding in HF. (b) Higher H—F bond dissociation enthalpy than H—Cl. (ii) As P—P single bond (213 kJ mol-1) in P4 is much weaker than...

(i)The bonding molecular orbital has lower energy and hence greater stability than the corresponding antibonding molecular orbital.  (ii) Just as the electron probability distribution around a nucleus in an atom is...

( a) In the molecules HCl, HBr and HI, dipole-dipole interaction and London forces are present.  (b) The dipole moment of HCl > HBr > HI but boiling point of HCl...

All the four valencies are satisfied by carbon.

(B) If both assertion and reason are true, but reason is not the true explanation of the assertion.
