The C-H bond distance is the longest in:
Correct answer: C. C2H6
- A. C2H4
- B. C2H2
- C. C2H6
- D. C2H2Br
Explanation
Higher the s− character means that the Bonded pair electrons are held more closely, ensuring a smaller Bond length and a stronger bond.So, sp has the least bond length and it is the strongest Sp3 has the longest bond length and weakest.So, C is the correct answer.
