Common mistake in drawing hydrogen bond

Common mistakes in drawing hydrogen bond

One of the most common mistakes is to write the dipole across the hydrogen bond, e.g.

A dipole exists as a pair, partial positive and partial negative. It also depicts the uneven electron density distribution in a covalent bond thus it first forms in a single molecule where
the hydrogen atom is bonded to a very electronegative element such as F/O/N. As the hydrogen is almost “stripped” bare of its electron, it is strongly attracted to the lone pair on a highly electronegative F/O/N atom. This electrostatic attraction is known as a hydrogen bond. e.g.

Another type of hydrogen bonding within the same molecule is known as Intramolecular hydrogen bonding. Which type is overcome during boiling?
