Question

What is the number of =N-OH groups present in dimethyl glyoximato?

• A. 3
• B. 4
• C. 1
• D. 2

Hint:

When analyzing a chemical structure, count the functional groups to identify their presence. Dimethyl glyoximato has two =N-OH groups.

Answer 1

The Correct Option is D

Step 1: Structure of dimethyl glyoximato.
Dimethyl glyoximato contains two =N-OH groups attached to the carbonyl group. Thus, there are two =N-OH groups present in the structure.

Step 2: Analyzing the options.
(A) 3: Incorrect, as there are only two =N-OH groups in the structure.
(B) 4: Incorrect, as there are only two =N-OH groups in the structure.
(C) 1: Incorrect, as there are two =N-OH groups in the structure.
(D) 2: Correct, as there are two =N-OH groups in dimethyl glyoximato.

Step 3: Conclusion.
The correct answer is (D) 2, as the compound contains two =N-OH groups.
