Question

Which of the $C-C$ bond is strongest

• A. Formed by $s{p}^3-s{p}^3$ hybridised carbon atoms (as in alkanes)
• B. Formed by $s{p}^2-s{p}^2$ hybridised carbon atoms (as in alkenes)
• C. Formed by $sp-sp$ hybridised carbon atoms (as in alkynes)
• D. All are equal

Answer 1

Answer: (C)

$sp-sp>s{p}^2-s{p}^2>s{p}^3-s{p}^3$
