Of the bonds C-C, C-C, and C≡C, the C-C bond is __________.
A)strongest/shortest
B)strongest/longest
C)weakest/longest
D)weakest/shortest
E)intermediate in both strength and length

Question

Quizplus · Accepted Answer

The C≡C bond is the strongest and shortest as it contains a triple bond. The two C-C bonds are weaker and longer as they only contain a single bond. Among the C-C bonds, the weaker and longer bond is weaker than the other C-C bond due to steric hindrance caused by the larger sized groups attached to each carbon atom, resulting in a longer bond length. Therefore, the correct option is C) weakest/longest.
