Question
How many σ-bonds are present in 3-methyl phenol?
Solution
6 carbon atoms of the ring form a sigma bond with the neighbouring carbon atoms of the ring. Therefore 6 sigma bonds. Another carbon atom forms a sigma bond with the carbon of -CH3 group which in turn forms a sigma bond with each of the 3 hydrogen atoms. 4 more sigma bonds.
4 carbon atoms of the ring form a sigma bond with hydrogen atoms. 4 more sigma bonds.
-OH form 2 sigma bond.
Total =6+2+4+4 =16 sigma bonds.
