Chapter 3: Q66P (page 138)

Draw a picture of the hydrogen bonding in methanol.

Short Answer

Expert verified

The hydrogen bond is the link established between a strongly electronegative atom that is oxygen, fluorine, and nitrogen and the hydrogen atom.

A dotted line represents a hydrogen bond (-----).

Methanol has the chemical formula CH3OH .

Step by step solution

01

 Definition of the hydrogen bond.

The hydrogen bond is the link established between a strongly electronegative atom that is oxygen, fluorine, and nitrogen and the hydrogen atom.
