Question

which of the following is incorrect for benzene​

Answer 1

The incorrect statement for Benzene is Benzene does not show addition reactions like alkenes due to the delocalisation of π-electrons.

Answer 2

Question:

Which of the following is incorrect for benzene​-

a. It is planar.

b. It is unstable.

c. It shows resonance hybrid.

d. It has a six membered ring structure.

Answer:

It is unstable (b)

Explanation:

• Benzene is a six membered cyclic hydrocarbon. All the carbon atoms in benzene are sp2 hybridized and thus Benzene is a planar molecule.

• Six C-C sigma bonds are formed when one of the two sp2 hybridized orbitals of one atom overlaps with the sp2 orbital of adjacent carbon atom. The combination of other left sp2 hybridized orbitals with s orbital of hydrogen forms six C-H sigma bonds. Remaining unhybridized p orbitals of carbon atoms form π bonds with adjacent carbon atoms by lateral overlap leading to the formation of two resonance hybrid kekular structure.
• Owing to the presence of resonance in the molecule Benzene is a very stable compound existing freely in nature.
