Strength and Length

Postby Aayush Patel 3B » Sun Nov 03, 2019 3:39 pm

Can someone explain the relationship between the length of the bonds and how the strength of those bonds increase or decrease accordingly?

Longer bonds are weaker (easily broken) and thus are more likely involved in reactions. These would be single bonds, and as you increase into double and triple bonds, they get stronger and shorter. Therefore, double bonds are shorter and stronger than single bonds and triple bonds are stronger and shorter than both double and single bonds.

The strength of a bond is measured by its dissociation energy. Longer bonds are easily broken and more likely to be involved in a reaction, while shorter bonds are harder to break and therefore less reactive. The longer the bond, the weaker it is.

Simply put, the longer the bond length, the weaker the bond & the shorter the bond length, the stronger the bond.

Longer bonds are easier to break. Shorter bonds are stronger since the attractions between the elements are stronger. Single bond is longer than double bond, and double bond is longer than triple bond. Therefore, single bond is weaker than double bond, and double bond is weaker than triple bond.

Essentially, the more bonds between two atoms just means that the electron density between the two are much higher than atoms with less bonds. Thus, the higher likelihood of electrons in the middle act to pull the positively charged nuclei of the atoms closer together, making it harder to break.

The longer the bond length, the weaker the bond is and the shorter the bond length, the stronger the bond is.

The longer the bond, the weaker the bond.

When in terms of double and single bonds, the double bonds are shorter and contain a stronger bond called a pi bond in addition to a sigma bond, opposed to just a sigma bond like the longer single bond contains.

As the length of a bond decreases, the strength of the bond increases.

Shorter bonds tend to be stronger bonds because the charged subatomic particles (protons and electrons) are in closer proximity to each other.

Why does the fact that charged subatomic particles (protons and electrons) are in closer proximity to each other make the bond sstronger?

Longer bonds generally mean they're weaker, and shorter bonds generally mean they're stronger.

The stronger the bond, the stronger the attraction between the two atoms, resulting in a shorter bond. Vice versa, when the bond is weak, the atoms are not as closely held together and therefore results in a longer bond.

Can someone explain how this is true? Arent molecules that have high electron density less stable because the electrons are all repelling each other?

Longer Bond=Weaker bond
Shorter Bond= Stronger bond

Put simply, the shorter a bond is, the stronger it is, and vice versa. To understand why this happens you need to consider the electron clouds of atoms. If the electron clouds of two atoms overlap, the bond will be stronger and also shorter. More overlapping is associated with stronger bonds and shorter lengths.

In general, the longer the bond length, the weaker it is. Also, multiple bonds results in short bonds meaning they are generally stronger.

The shorter the bond, the stronger it is.
