Question

(A) : The C, C bond length in benzene is intermediate between C, C single bond length and C, C double bond length.
(R) : Benzene molecule exhibits resonance.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A)
• B. Both (A) and (R) are true and (R) is not the correct explanation of (A)
• C. (A) is true but (R) is false
• D. (A) is false but (R) is true

Answer 1

The correct option is A Both (A) and (R) are true and (R) is the correct explanation of (A)

Due to delocalisation of pi electrons of double bond, all C-C bond length of benzene are equal and this delocalisation process is called resonance.
