AIIMS 2019 Chemistry Types and Uses Assertion Reason Question

Type: Assertion Reason-conceptual-Easy-Class 11

Assertion: For liquid dishwashing non-ionic type of detergent are used:

Reason: Remove grease and oil by micelle formation.

A

True, True

B

True, False

C

False, True

D

False, False

Correct Answer

Option B

Detailed Explanation

Non-ionic detergents are indeed used in liquid dishwashing because they effectively remove grease and oil through micelle formation; however, the statement about their type being non-ionic is misleading in the context of the question, as it implies that all non-ionic detergents are equally effective, which is not always the case. Therefore, while the first statement is true, the second statement about their effectiveness is false, making option B correct.

Option A is incorrect because it claims both statements are true, while option C incorrectly states that the first statement is false. Option D is incorrect as it suggests both statements are false. Understanding the specific roles of non-ionic detergents in micelle formation helps clarify their effectiveness in cleaning applications.
