Question
Chapter 3, Problem 66P
Interpretation Introduction
Interpretation:
The picture of the hydrogen bonding in methanol has to be given.
Concept introduction:
Hydrogen bonding: It is a
This type of bonding does not sharing of electrons in a covalent bond, it is attraction between the positive and negative poles of charges atoms.
Polarity: It is a well separation of electric charge leading to a molecule or chemical compounds having an electrical dipole moment. Generally the polar molecules must contain polar bonds due to a different in electronegative between the bonded atoms.
