Question 1
4 / -1

Sulphur reacts with chlorine in 1 : 2 ratio and forms X. Hydrolysis of X gives a sulphur compoundY. What is the hybridization state of central atom in the compound Y?

A
sp³

B
sp²

C
sp

D
dsp²

Solution

Hybridisation of S in H₂SO₃ = 1/2 (6+2+0) = 4 = sp³ (3σ + 1π)

A

B

C

D
none of these

Solution
Question 3
4 / -1

50 ml of a solution containing 10^-3 mol of Ag⁺ is mixed with 50 ml of a 0.1 M HCl solution. Howmuch [Ag⁺] remains in solution? Given: K_sp of AgCl = 10^-10

A
2.5 X10^-9M

B
2.5 X10^-7M

C
2.5 X10^-8M

D
2.5 X10^-10M

Solution
Question 4

Where X is a compound that forms azodye with benzene diazonium chloride in faintly basic medium.

Hence the products P, X and Y are respectively.

A

B

C

D

Solution
Question 5
4 / -1

Which of the following solutions show lowering of vopour pressure on mixing?

A
Aniline and cyclohexane

B
Chloroform and acetone

C
Dimethyl ether and chloroform

D
option B and option C are correct

Solution

In B and C compound after mixing undergoes H – bonding and hence boiling point will be raised and hence vapour pressure lowered.

A

B

C

D
All options are correct

Solution
Question 7
4 / -1

Directions For Questions

A’ is a substance that converts into B, C and D by three first order parallel paths simultaneously according to the following stoichiometry

The partial t_1/2 of A along path I and path II are 173.25 min and 346.5 min respectively. The energies of activation of the reaction along path I, path II and path III are 40, 60 and 80 kJ/mol respectively.

The percent distribution of C in the product mixture B, C and D at any time is equal to

A
20

B
60

C
80

D
40

Solution

If k₁, k₂ and k₃ be the rate constants of the reaction along path I, II and III respectively, then overall rate constant of consumption of A will be k₁ + k₂ + k₃. So,
