Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

There are 6 C-C σ bonds, 6 C-H σ bonds, and 3 C=C π bonds. This makes 16 bonding orbitals. According to molecular orbital theory, the σ molecular orbitals form from the three sp² orbitals on each carbon atom and the 1s orbitals on each hydrogen atom. These 24 atomic orbitals mix to form 24 molecular σ orbitals. Of these, 12 are bonding σ orbitals and 12 are antibonding σ* orbitals. The 6 atomic p orbitals on the carbon atoms mix to form 6 molecular π orbitals. Resonance helps to keep the balance in the molecules and regulates 6 p atomic orbitals. For basics I will suggest you to study kekule model for benzene.
