Question

Which of the following statements is true for pyran?

• A. It is saturated aliphatic compound
• B. It is homocyclic compound
• C. It is heterocyclic with oxygen atom in ring
• D. Molecular formula of pyran is \( \mathrm{C_5H_5S} \)

Hint:

Heterocyclic compounds contain at least one atom other than carbon in the ring.

Answer 1

The Correct Option is C

Step 1: Understanding pyran.
Pyran is a six-membered ring compound containing one oxygen atom and five carbon atoms.

Step 2: Nature of the ring.
Since an oxygen atom is present in the ring, pyran is classified as a heterocyclic compound.

Step 3: Elimination of incorrect options.
It is not saturated, not homocyclic, and its correct molecular formula is \( \mathrm{C_5H_6O} \), not sulfur-containing.

Step 4: Conclusion.
Therefore, the correct statement is that pyran is heterocyclic with an oxygen atom in the ring.
