Detailed explanation-1: -Which of the following characteristics of water is not a result of hydrogen bonding? All of the above are a result of hydrogen bonding.

Detailed explanation-2: -Which of the following is not a property of water that results from hydrogen bonding? Water has a high surface tension.

Detailed explanation-3: -Water’s high heat capacity is a property caused by hydrogen bonding among the water molecules.

Detailed explanation-4: -Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.

Detailed explanation-5: -(d) Polar nature of halogen acids (HX) is due to the electronegativity difference between H and halogen atoms. Except Fluorine, other halogens do not show H-bonding due to their large sizes and diffused electrons, reducing the charge density that is required for H-bonding.
