Concept explainers
(a)
Interpretation:
The dipole moments of the three dimethylbenzenes have to be given.
Concept Introduction:
Polar covalent bond involves an unequal sharing of electrons between two bonded atoms; it creates a partial separation of charge and a dipole moment.
Covalent bonds are polar, if there is a difference in electronegativity between the bonded atoms.
Calculation of the dipole moment of polyatomic molecules:
(b)
Interpretation:
The dipole moments of the given trimethylbenzenes have to be given.
Concept Introduction:
Polar covalent bond involves an unequal sharing of electrons between two bonded atoms; it creates a partial separation of charge and a dipole moment.
Covalent bonds are polar, if there is a difference in electronegativity between the bonded atoms.
Calculation of the dipole moment of polyatomic molecules:
(c)
Interpretation:
The values which are sure should be given.
Concept Introduction:
Polar covalent bond involves an unequal sharing of electrons between two bonded atoms; it creates a partial separation of charge and a dipole moment.
