• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Benzene can be drawn as a series of resonance structures, its bonds are hybrids of single and double bonds. The classical example in resonance structures is the benzene ring. Benzene is a ring of 6 carbon atoms with conjugated double bonds (i.e. alternating single and double bonds). When drawing the ring, the double bonds can be located in 2 different positions as shown in fig. 1. Both are equally right and wrong. The double bond between position 1 and 2 is there some of the time, but on average there is really 1.5 bonds between all the carbons. The bond is said to be delocalized, which is why the benzene ring is often written as a hexagon with a circle. The difference from rearranging the electrons is called resonance structures, and the change between structures is shown by a single arrow pointing both ways.
