Question

Is $C{{H}_{3}}-C{{H}_{3}}$ a hydrogen bond?

Answer 1

Hydrogen bond is a type of intermolecular force between the compound and hydrogen bond formed between the hydrogen atom and the atoms that have high electronegativity which is placed on the right side of the periodic table.

Complete step-by-step answer: A hydrogen bond is a type of intermolecular force between the compound and hydrogen bond formed between the hydrogen atom and the atoms that have high electronegativity which is placed on the right side of the periodic table. A hydrogen bond is a very strong bond.
The hydrogen bond is formed only between hydrogen and the three most electronegative elements, i.e., fluorine, oxygen, and nitrogen. In hydrogen fluoride, water, and ammonia hydrogen bonding is present.
$C{{H}_{3}}-C{{H}_{3}}$ is an organic compound whose name is ethane and there is no hydrogen bond present in ethane because of the electronegativity of carbon and a hydrogen atom. The electronegativity of carbon and hydrogen are very similar. And hydrogen bonds can only exist in those compounds having large electronegativity differences.
So, the force which exists between the ethane is the London Dispersion forces. This force is produced due to the momentary dipole produced in the compound. In these compounds, the dipole moment is for a very short time and to a very small extent. London Dispersion force is a weak force as compared to the hydrogen bond.
Therefore, $C{{H}_{3}}-C{{H}_{3}}$ doesn’t have hydrogen bonding.

Note: There are two types of hydrogen bonding which are classified on the type of interaction, if the interactions are between different molecules then it is intermolecular hydrogen bonding, and if the bonding is within the molecule, then it is intramolecular hydrogen bonding.
