The carbon-carbon bond distance in benzene is
Options
- ALonger than a C - C single bond
- BLonger than a C = C double bond
- CShorter than a C = C double bond
- DShorter than a C ≡ C triple bond
Correct answer
B. Longer than a C = C double bond
Step-by-step solution
The bond order of carbon-carbon bond is 1 .5 in benzene. Hence, carbon-carbon bond distance (1 .397 A o ) is less than C = C single bond (1 .33 A o ) . and more than C = C double bond ( 1.33 A o )
