how many pi bond and sigma bond are there in benzene?
Answers
Between every two bonded atoms there is a sigma bond. It is the most basic of all bonds as it is directly between two atoms. If you drew a straight line between two atoms, you would cross where the sigma bond is placed. So the big question is where would the second or third bond in a double bond or triple bond be placed since you cannot place two bonds in the same place? These bonds are formed by overlap of the p-orbitals. If you recall from chemistry, the p orbital has a peanut shape. This is what we call a pi bond.
Without going into too much more detail, to answer your question, there is a sigma bond between every atom in benzene. There is also an addition bond called a pi bond present wherever there is a double bond. This leads to 12 sigma bonds (do not forget the hydrogens) and 3 pi bonds. It should be noted that the pi bonds are in a conjugated system and rotate around the ring which gives stability to benzene.
