Assertion:Micelles are formed by surfactant molecules above the critical miceller concentration (CMC). Reason: The conductivity of a solution having sufficient molecules decreases sharply at the CMC.

A

If both (A) and (R) are correct, and (R) is the correct explanation of (A)

B

If both (A) and (R) are correct, but (R) is not the correct explanation of (A)

C

If (A) is correct, but (R) is incorrect

D

If (A) is incorrect, but (R) is correct

Text Solution

Verified by Experts

The correct Answer is:
B
The formation of micelles takes place above CMC. Each micelle contains at least 100 molecules. Hence, conductivity of the solution decreases sharply at the CMC.

Which of the following forms cationic micelles above certain concentration?

Assertion : Molar conductivity increases with decrease in concentration. Reason:Conductivity always decreases with decrease in concentration.

Assertion : Osnosis involves movement of solvent molecules from its lower concentration to its higher concentration. Reason : Solutions having the same osmotic pressure are called isotonic solutions.

Assertion: H _(2) molecule is more stable than He-H molecule. Reason: The antibonding electron in He-H molecule decreases the bond order and thereby stability

Assertion: A gas can be easily liquified at any temperature below its critical temperature. Reason : Liquifaction of gas takes place when the average kinetic energy of the molecule is low.

Assertion : The boiling point of chloroform-acetone solution is larger than expected from ideal behaviour. Reason : The forces of attraction between unlike molecules are stronger than those between like molecules in the solution. This results in lower vapour pressure as compared to an ideal solution which is responsible for the higher boiling point.
