Question

Identify the number of carbon atoms and number of oxygen atoms respectively present in pyran molecule.

• A. 5 and 2
• B. 6 and 1
• C. 4 and 2
• D. 5 and 1

Hint:

Pyran is a heterocyclic compound with five carbon atoms and one oxygen atom, making it important in organic chemistry.

Answer 1

The Correct Option is D

Step 1: Understanding the structure of pyran.
Pyran is a six-membered heterocyclic compound with five carbon atoms and one oxygen atom. The structure contains five carbon atoms (C) and one oxygen atom (O).
Step 2: Analyzing the options.
(A) 5 and 2: Incorrect. Pyran has one oxygen atom, not two.
(B) 6 and 1: Incorrect. Pyran has five carbon atoms, not six.
(C) 4 and 2: Incorrect. Pyran has five carbon atoms, not four.
(D) 5 and 1: Correct. Pyran has five carbon atoms and one oxygen atom.
Step 3: Conclusion.
The correct answer is (D) 5 and 1, as pyran contains five carbon atoms and one oxygen atom.
