Re: strength of bonds
The strength of a bond is affected by the charge and distance for ionic bonds. The strength of a bond is affected by the electronegativity differences and the bond length. Generally, double bonds are stronger than single bonds and triple bonds are stronger than double bonds. We will probably need to know the energy of the bond, which is going to be the enthalpy of bonds broken minus the enthalpy of bonds formed

Re: strength of bonds
Usually shorter bonds (in distance, Angstroms) are stronger than longer bonds.

Re: strength of bonds
I think Professor Lavelle hasn't gone over it in class yet but there should be a formula or methodology to calculating bond length (primarily looking at single, double, and triple bonds in a lewis dot structure diagram) and thus will help determine bond strength.

Re: strength of bonds
I'm not quite sure if there is a value that we use to determine bond strength I think just remembering that as the number of bonds increase, so does its strength so the strongest bonds are triple bonds>double bonds>single bond with single bonds being the weakest.

Re: strength of bonds
Triple bonds are shorter than double bonds because there are more attraction forces and they tend to be stronger. Double bonds are shorter and stronger than single bonds because of the same reason.

Re: strength of bonds
In terms of electrons, what is the difference between a triple bond, a double bond, and a single bond?

Triple bonds represent three pairs of electrons. Double bonds represent two pairs of electrons. Single bonds represent one pair of electrons.

Re: strength of bonds
yes, strength does correlate to melting points. The stronger the bond, the more energy required to break it, thus the higher the temp/energy required

Ionic bonds are stronger than covalent bonds because they involve the trtansfer. of electrons rather than a sharing of electrons.

A good rule of thumb is that typically the stronger the bond is, the shorter it will be in length.
Triple bonds are the shortest of the bond types and have 3 pairs of electrons. Due to the 3 electron pairs, they are also the strongest.
This is followed up by double bonds which have 2 pairs of electrons.
Single bonds are the weakest in strength of the 3 and only contain 1 electron pair; however, they are also the longest.

Yes, it does! Since more energy is needed to break stronger bonds, bonds that break with higher melting points would suggest that more energy is required to break the bonds.
