strength of sigma and pi bonds

[Alysia Garcia 1B]

Would a sigma bond be stronger than a pi bond and why?

[Shione Nakahara 1F]

Yes, a sigma bond is stronger than a pi bond. This is because the length of a sigma bond is shorter than a pi bond, and it takes more energy to break a sigma bond.

Pi bonds have a sideways overlap while sigma bonds have an axial overlap. Axial overlaps have a higher amount of overlapping than sideways overlaps do.

[Chiara Berruto 1K]

sigma bonds are able to rotate on their axis and are a stronger where as pi bonds would break if they were rotated

[Cameron Smith 1I]

What occurs when pi bonds are broken?

[Raquel Floyd 1K]

Whenever a bond breaks that is then classified as a chemical reaction. So if a pi bond breaks, the molecule has then undergone a chemical reaction.

[Cindy Nguyen 1L]

Yes, a sigma bond is stronger than a pi bond. This is because the length of a sigma bond is shorter than a pi bond, and it takes more energy to break a sigma bond.

Because a double bond is a sigma bond and a pi bond and every type of chemical bond has to have at least one sigma bond, how are double bonds shorter than single bonds then?

[Sonia Aronson 1B]

I think a double bond is stronger than a single bond because the two p orbitals overlap and pull the atoms closer together.

[Joanna Pham - 2D]

Yes, a sigma bond is stronger than a pi bond. This is because the length of a sigma bond is shorter than a pi bond, and it takes more energy to break a sigma bond.

Wait but aren't sigma bonds single bonds? Wouldn't sigma bonds be weaker since single bonds are weaker than double bonds (which is what the pi bonds are)?

Why do Pi bonds break when they rotate?

[Amanda 1A]

since pi bonds are caused by side-to-side overlapping where there is much less overlap due to the orbital paths being parallel, they are easier to break than sigma bonds that overlap head-to-head.
