Question

When bonded to fluorine, oxygen, or nitrogen, hydrogen can participate in a form of strong non-covalent bonding called 'hydrogen bonding', which is critical to the stability of many biological molecules. It is also that these 'hydrogen bonds' that account for many of the unusual properties of water.

A. True
B. False

Answer 1

Hydrogen bonding occurs when hydrogen is bonded to fluorine, oxygen, or nitrogen. This form of strong non-covalent bonding is critical for the stability of biological molecules and contributes to the unusual properties of water.

Step-by-step explanation:

Hydrogen bonding occurs when hydrogen is covalently bonded to fluorine, oxygen, or nitrogen. These elements withdraw electron density from the hydrogen atom, making it electron-deficient and exposed. This allows for strong attractions with nearby lone pairs of electrons, resulting in a form of strong non-covalent bonding called hydrogen bonding. Hydrogen bonding is critical for the stability of many biological molecules and is responsible for many of the unusual properties of water.
