### bond strength

Why are pi bonds weaker than sigma bonds even though they make double bonds stronger?

### Re: bond strength

I read that pi bonds are weaker than sigma bonds because they overlap side to side rather than end to end. So the pi bond is weaker because there is less overlap.

Pi bonds are weaker because there orbital paths are parallel which results in the overlap between the p-orbitals to be less than those of sigma bonds.

Yeah, so even though the pi bond is weaker, it does provide some strengh to the existing bond, so it results in a double bond that would be stronger the sigma alone.
