Effect of size of bond between carbon and leaving group

[Monkeydfdg64]

I have a card that states that leaving group strength increases as bond between carbon and leaving group decreases. I thought it was the other way around.

Your card is correct, I think. As the bonds between a carbon and a leaving group DECREASES, the strength of a leaving group becoming independent increases. In other words, if a bond is DECREASING in strength, it WEAKENS and there's a higher chance it will ACTUALLY break. The semantics of it all may be confusing you.

Thanks I realized that bond doesn't mean bond length. That helps clarify.
