MCQ
The number of $sp^2 - s$ sigma bonds in benzene are
- A$3$
- ✓$6$
- C$12$
- Dnone of these
✓
Answer
Correct option: B.
$6$
b
Benzene has molecular formula $\mathrm{C}_{6} \mathrm{H}_{6}$ that is there is the presence of a double bond in between alternate carbon atoms and each carbon is attached to two carbon atoms by means of a single bond and a double bond and a hydrogen atom by a single bond.
Benzene has molecular formula $\mathrm{C}_{6} \mathrm{H}_{6}$ that is there is the presence of a double bond in between alternate carbon atoms and each carbon is attached to two carbon atoms by means of a single bond and a double bond and a hydrogen atom by a single bond.
So there are a total of 12 sigma bonds and 3 pi bonds in benzene. The carbon atoms are bonded through $\mathrm{sp}^{2}-\mathrm{Sp}^{2}$ overlap while six $\mathrm{C}-\mathrm{H}$ bond is formed by $\mathrm{sp}^{2}-\mathrm{s}$ sigma bond.
Thus there is $6 \mathrm{sp}^{2}-\mathrm{s}$ sigma bond.
