Solution:
QUESTION: 5

Solution:
QUESTION: 6
The vapour pressure of a solvent decreased by 10mmHg when a nonvolatile solute was added to the solvent. The mole fraction of the solute in the solution
is 0.2. What would be the mole fraction of the solvent if the decrease in the vapour pressure is to be 20 mmHg
Solution:
The equation governing the change in the vapor pressure when you use a nonvolatile liquid or solid is just a special case of Raoult's Law, Ptot = PaXa + PbXb. Since the second component has a negligible vapor pressure (nonvolatile), Raoult's law reduces to

P = P0X
where P is the vapor pressure of the mixture, P0 is the vapor pressure of the pure solvent and X is the mole fraction of the solvent.
Mole fraction of solute = 0.2
so mole fraction of solvent = 0.8 
So
P-10 = 0.8(P)
So P= 10/0.2 = 50
 
In second case
50-20 = x.50
30/50= x
So mole fraction of solvent = 0.6
QUESTION: 7

Ethyl chloride is converted into diethyl ether by

Solution:
QUESTION: 8

A metal crystallizes with a face-centered cubic lattice. The edge of the unit cell is 408 pm. The diameter of the metal atom is

Solution:
For an FCC cubic lattice:
r=a√2/4
where,
r is the radius of atom
a is the edge length of unit cell   
r=408x1.414/4 
=144.228 pm
Therefore, diameter of metal atom = 2 x 144.228 pm = 288.456 pm

The utility of the polymers in various fields is due to their mechanical properties like tensile strength,elasticity, toughness etc.These properties mainly depend upon intermolecular forces like van der Waal’s forces and hydrogen bonding operating in polymer molecules. Polymers have been classified on this
basis,e.g.(1) Elastomers (2) Thermoplacstics (4) Thermosetting. Hence
The molecular forces of attraction are weakest in
