Question

Which of the following compounds can act as a base?

• A. NH\(_4\)OH
• B. NH\(_3\)NH\(_2\)
• C. NH\(_2\)OH
• D. CH\(_3\)OH

Hint:

Bases are proton acceptors, and ammonium hydroxide is a common base used in chemical reactions.

Answer 1

The Correct Option is A

Step 1: Understanding the Question.
The question asks which compound can act as a base. Bases are substances that can accept protons or donate electron pairs.
Step 2: Analyzing the Options.
- (A) NH\(_4\)OH is an ammonium hydroxide solution, which acts as a base by accepting protons.
- (B) NH\(_3\)NH\(_2\) is a compound with amine groups but not a strong base in this context.
- (C) NH\(_2\)OH is hydroxylamine, which is a weak base.
- (D) CH\(_3\)OH (methanol) is a weak acid, not a base.
Step 3: Conclusion.
The correct answer is (A) NH\(_4\)OH.
