The physical properties of a compound depend upon the number and nature
of _______ constituting its structural units
Atoms
In _______compounds, the positive and negative ions are held together by
strong electrostatic forces.
Ionic
In ionic compounds, the positive and negative ions are held together by strong
_______ forces.
Electrostatic
In _______compounds, the molecules are held together by intermolecular
forces.
Covalent
In covalent compounds, the molecules are held together by _______forces.
Intermolecular
The three important intermolecular forces are:
(i) dipole-dipole interactions
(ii) London forces
(iii) Hydrogen bonding
_______ are defined as the interactions between the different molecules of a
compound having permanent dipoles.
Dipole-Dipole Interactions
The dipole-dipole interactions are weak interactions
True
The intermolecular interactions which exist between no polar molecules is
known as_______
London forces
When the molecules A and B approach each other, there is a distortion in the
distribution of the charge resulting in a small and momentary dipole in one
molecule. This small dipole can then create another dipole in the second
molecule which is called________.
Induced dipole
The induced dipole – induced dipole interaction are also known as_______.
