1. How we expect which bond is stronger, consider only single bond? 

C - C, C - N, C - F, C - O.

Is there trend?

Someone said to me that polarized bond is weaker than nonpolarized bond.

Is it right?

2. I know that increasing orbital overlapping, bond strength is also increased. 

How about polarized bond? I think that in polarized bond, orbital overlapping is increasing, with attached file 1.

and then, polarized bond is stronger than nonpolarized bond??

3.How we expect which functional group is good leaving group?

4. Is there any relationship between good leaving group and bond strength?

I mean that for example in attached file 2,  Br is leaving group, because C - Br is weaker bond than C - C bond.

Is it right?
