The length of C - C bond in benzene is
Options
- A1.22 Å
- B1.54 Å
- C1.39 Å
- D1.56 Å .
Correct answer
C. 1.39 Å
Step-by-step solution
The bond length C - C (single bond as in ethane) is 1.54 ~A and C = C (double bond as in ethene is 1.33 Å . The carbon carbon bond length in benzene has been found to be 1.39 Å which lies between single and double bond length value.
