Question
Chapter 7, Problem 70P
Interpretation Introduction
(a)
Interpretation:
The type of intermolecular force exhibited by ethanol and dimethyl ether needs to be determined.
Concept Introduction:
The intermolecular force is defined as the force which occurs between the one molecule to another as attraction. The intermolecular force is of following types −
- Hydrogen bond this type of intermolecular force exists in that molecule in which the hydrogen atom is covalently bonded with the atom with high electronegativity and it has strong intermolecular attraction.
- Dipole-Dipole interaction is a type of intermolecular force occurs only in the polar molecules and increase with the polarity of the molecule.
- London Dispersion intermolecular force occurs in the polar or non-polar molecule or atoms.
Interpretation Introduction
(b)
Interpretation:
The compound with higher boiling point between ethanol and dimethyl ether needs to be determined.
Concept Introduction:
The intermolecular force is defined as the force which occurs between the one molecule to another as attraction. The intermolecular force is of following types −
