Why Are Double Bonds Shorter

[Mark 1D]

Howdy partners. What is the reasoning for why double bonds are shorter (and therefore stronger) than single bonds? Thanks

[Diana Bibireata 1B]

Its because the additional bonding electrons in a double bond attract the nuclei more strongly and pull the atoms closer together.

[Linh Vo 2J]

The textbook in section 2.16 page 83 says, "Multiple bonds are shorter than single bonds between the same two elements because the additional bonding electrons attract the nuclei more strongly and pull the atoms closer together.” This should help clarify your question!

[Sapna Ramappa 1J]

Double bonds would be shorter (and thus stronger) because there are more electrons that are bonding, and as a result, the atoms are pulled closer together.

^^^ more electrons have more pull and make the bond shorter

[Kaylee Clarke 1G]

double bonds are shorter than single bonds, and triple bonds are shorter than single bonds because the greater number fo the bond the more closely is it attracted to the nucleus, decreasing the atomic radius.

[205154661_Dis2J]

Double bonds are shorter because the pull/attraction to the nucleus is greater than single bonds.

[105311039]

Double bonds are closer because they have a stronger bond, so they pull the elements closer together.

[605136321]

single bonds are longer because there is less attraction to the nuclei, whereas double bonds have a greater pull and thus are pulled closer making them shorter

Should we also know the relative strengths of polar covalent vs non polar covalent forces

[Joanne Lee 1J]

Double bonds are shorter than single bonds because double bonds are stronger and therefore pull the electrons closer together in the two elements which decreases the length of the bond.

[Vanessa Chuang 4F]

For the midterm we just took, there was no need to really know the difference. But in the future for the next test and the final, we will have to know the difference between poplar covalent and non polar covalent forces as well as the differences in their strengths, characteristics, etc.

There are more electrons involved in the bond hence there is a stronger attraction between the atoms. They are pulled closely so the length of the bond shortens compared to a single bond where only 2 electrons are being shared.

[emma brinton_3B]

this is because with the addition of more electrons between the pairs, the pull of the two atoms together is stronger and thus shortens the length of the bond.

[Juana Abana 1G]

Double bonds are shorter and stronger since the electrons between the two elements are pulled closer together.

[Lauren Sanchez 3D]

So triple bonds pull the nuclei even closer then? Which then makes them even stronger than double bonds?

[Daniel Honeychurch1C]

So triple bonds pull the nuclei even closer then? Which then makes them even stronger than double bonds?

Yes, in triple bonds, there are 6 shared electrons which pulls the two atoms even closer than in double bonds which makes triple bonds stronger and harder to break (more energy is needed).
