Which one of the following has shortest carbon-carbon bond length here?
Options
- AC 6 H 6
- BC 2 H 4
- CC 2 H 2
- DC 2 H 6
Correct answer
C. C 2 H 2
Step-by-step solution
C 2 H 2 has a triple covalent bond ( ≡ ) , which has shortest bond length. Here C - C bond length order is C 2 H 6 > C 6 H 6 > C 2 H 4 > C 2 H 2
