How many sigma bonds and pi bonds are there in an anthracene molecu How many valence electrons occupy sigma-bond orbitals and how many

Draw the structure of anthracene and count the number sigma bonds, number of pi bonds, and number of valence electrons. Also identify the hybridization of carbon atoms present in anthracene.


Identify the hybridization of an atom by counting the number of sigma bonds.

If carbon is attached with 4 sigma bonds then the hybridization is sp3 ms mp^3sp3 .

If carbon is attached with 3 sigma bonds then the hybridization is sp2 ms mp^ m2sp2 .

If carbon is attached with 2 sigma bonds then the hybridization is sp mspsp .


The molecular formula of anthracene is C14H10 mC_ m14 mH_ m10C14​H10​ .
