Number of bonds and σ bonds in the following structure is–
(i) 6, 19
(ii) 4, 20
(iii) 5, 19
(iv) 5, 20
The answer is the option (iii) 5, 19
Explanation: Here, each C atom is sp2 hybridized and surrounded by 3 sigma bonds and 1 pi bond between two C atoms.
8 C – H + 11 C – C bonds = 19 bonds.
There are - bonds and 19 bonds.
