In which of the following substances will molecules be held together by hydrogen bonding? acetic acid, acetone, or hydrazine

Acetic acid and hydazine

Explanation:

Hydrogen bonding is weak electrostatic force existing between a hydrogen atom covalently bonded to electronegative atoms and another elcetronegative atom.

Most commonly, compounds having hydrogen bonded to N, F and O atoms show hydrogen bonding.

Hydrogen bonding can be intermolecular and intramolecular.

Among the given option, acetic acid and hydrazine have hydrogen bonding.

Molecular formula of acetic acid is , so only acetic has hydrogen bonded to electronegative atom 'O'.

Molecular formula of acetone is . It has no hydrogen bonded to electronegative atom.

Molecular formula of hydrazine is . In this molecule, hydrogen is bonded to electronegative atom 'N'.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
