see diagram.
we can have two possible structures for C6 H12..
Between two atoms the first bond formed is a sigma bond. If there is a second bond, then it is a pi bond. A third bond between two atoms is also a Pi bond. A double bond consists of a sigma and a Pi bond. Triple bond consists of a sigma and two Pi bonds.
In the first structure there is a Pi bond possible. There are 17 sigma bonds.
formula for Pi bonds: (6 n + 2 - N)/2 :
n = number of atoms that can form sigma bonds. Here only Carbon atoms can. So n = 6.
N = number of valence electrons total in the molecule. = 4 * 6 + 12 = 36
So number of Pi bonds: (6 * 6 + 2 - 36) / 2 = 1
=================
2nd structure : there are 18 sigma bonds. It is a ring structure with all bonds being identical sigma bonds.
there are no pi bonds here.
