Question

Hydrogen bond between two atoms is formed due to

• A. Displacement of electrons towards more electronegative atom resulting in fractional positive charge on hydrogen
• B. Displacement of electrons towards hydrogen atom resulting in a polar molecule.
• C. Formation of a bond between hydrogen atoms of one molecule and the other.
• D. Existence of an attractive force which binds hydrogen atoms together.

Answer 1

Answer: (A)

Displacement of electrons towards more electronegative atom resulting in fractional positive charge on hydrogen

Answer 2

: Hydrogen bonding occurs when H atom is linked to an electronegative atom like F, O or N. it is the force of attraction between small positive charge developed on H atom and small negative charge developed on electronegative atom due to displacement of electrons towards more electronegative atom.
