Choose the answer that ranks the following species in order of increasing carbon-carbon bond strength(strongest bond last):C2H4 C2H2 C2H6

Choose the answer that ranks the following species in order of increasing carbon-carbon bond strength

(strongest bond last):

C2H4 C2H2 C2H6

Weakest Strongest

A. C2H4 < C2H6 < C2H2

B. C2H6 < C2H4 < C2H2

C. C2H2 < C2H6 < C2H4

D. C2H2< C2H4 < C2H6

E. C2H6 < C2H2 < C2H4

Solution: We must begin by drawing the correct lewis dot structures.

Next, we need to know that a triple bond is stronger than a double bond which is stronger than a single bond. Choice B is the correct answer choice.
