Question:
The number of \(\sigma\) bonds in carbolic acid are
The number of \(\sigma\) bonds in carbolic acid are
Show Hint
Every single bond is a sigma bond; double bonds contain one sigma and one pi bond.
Updated On: Feb 18, 2026

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Identify carbolic acid.
Carbolic acid is phenol with molecular formula \(\mathrm{C_6H_5OH}\).
Step 2: Count the sigma bonds.
In the benzene ring, there are 6 \(\mathrm{C{-}C}\) sigma bonds and 5 \(\mathrm{C{-}H}\) sigma bonds.
The \(\mathrm{C{-}O}\) bond contributes 1 sigma bond and the \(\mathrm{O{-}H}\) bond contributes 1 sigma bond.
Step 3: Total sigma bonds.
\[ 6 + 5 + 1 + 1 = 13 \]
Step 4: Conclusion.
Thus, carbolic acid contains a total of \(13\) sigma bonds.
Carbolic acid is phenol with molecular formula \(\mathrm{C_6H_5OH}\).
Step 2: Count the sigma bonds.

Step 4: Conclusion.
Thus, carbolic acid contains a total of \(13\) sigma bonds.
