Question

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

Answer 1

Acetic acid and hydazine

Step-by-step 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
`CH_3COOH`, so only acetic has hydrogen bonded to electronegative atom 'O'.

Molecular formula of acetone is
`CH_3COCH_3`. It has no hydrogen bonded to electronegative atom.

Molecular formula of hydrazine is
`N_2H_4`. In this molecule, hydrogen is bonded to electronegative atom 'N'.
