Only the hydrogen atom attached to the oxygen atom is capable of forming hydrogen bonds. A dipole does not form between the hydrogen and carbon atoms.
Option
Hydrogen bonding is an intermolecular force that forms when the dipole-dipole attraction is when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons.
This bonding mainly occurs between hydrogen and elements such as Oxygen, Fluorine, and Nitrogen.
For ethanol molecule (C2H5OH), hydrogen bonding occurs between the hydrogen and oxygen element as shown:
Hence we can conclude that only the hydrogen atom attached to the oxygen atom is capable of forming hydrogen bonds. A dipole does not form between the hydrogen and carbon atoms.
