Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A hydrogen bond is a weak attraction between a hydrogen atom and a polar molecule, which is the main reason water is liquid at room temperature.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -These bonds are extremely polar because of the high electronegativity difference between the atoms. This strong polarity causes very strong dipole-dipole interactions between molecules, called hydrogen bonding. Hydrogen bonds are weaker than chemical bonds.

Detailed explanation-2: -Thus, a weak attraction between a hydrogen atom in one molecule and an oxygen in another is called hydrogen bonding.

Detailed explanation-3: -hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces.

Detailed explanation-4: -Cohesion: Hydrogen Bonds Make Water Sticky Water has an amazing ability to adhere (stick) to itself and to other substances. The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a “sticky” liquid.
