Question
Chapter 3.7, Problem 25P
(a)
Interpretation Introduction
Interpretation:
Between the given molecules the compound that can form hydrogen bonding has to be identified.
Concept introduction:
Hydrogen bonding: It is an
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.
(b)
Interpretation Introduction
Interpretation:
The compound that forms hydrogen bonds with a solvent such as ethanol has to be predicted.
Concept introduction:
Hydrogen bonding: It is a electromagnetic attraction between polar molecules with hydrogen bonds to a larger atom (for example oxygen or nitrogen) atoms.
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.
