Question

SECTION - A
I. Read the parege given below and answer the following questions 11 xl = 11
1. Intermolecular forces are the forces of attraction and repulsion between interacting particles have
permanent dipole moments
This interaction is stronger than the London forces but is weaker than ion-ion interaction because only
partial charges are involved
The attractive forces decrease with the increase of distance between dipoles
The interaction energy is proportional to Lr where r is the distance between polar molecules.lon-
Dipole Interaction: This is the force of attraction which exists between the ions (cations or anions) and
polar molecules. The ion is attracted towards the oppositely charged end of dipolar molecules.
The strength of attraction depends upon the charge and size of the ion and the dipole moment and the
size of the polar molecule.
For example: Solubility of common salt (NaCl) in water.
The following questions are multiple choice questions. Choose the most
appropriate answer:
() Attractive intermolecular forces are known as
a Van der Waals forces
b. Dispersion force
c Repulsive force
d. None of the above
Dipole - Dipole forces act between the molecules possessing
a Attractive interaction
b. Permanent dipole
c Cumulative effect
d. Temporary dipole
(in) Standard temperature (STP) and pressure means
a 275.156,32°C 5Bar
b. 238. 15K,50°C.10 Bar
c275.15K,0°C,0Bar
d. 273.156.0°C 1 Bar
(iv) Kelvin scale of temperature is also called
a. constant scale
b. Thermodynamic scale
c. Relationship scale
d. Degree of scale​
