Bond energies
« on: October 26, 2006, 12:25:28 PM »
I'm currently doing coursework on the combustion of the four most basic alcohols... I need to work out calculations for energies?

Does anyone know where I can find bond energies?...

I've tried a library even they don't have 'chemistry' books... And when I compare bond energies from two different sites they are completely different!  Arghhh! Please help me...

Are they just in different units?

There's a table on this page.

Check the units on these sites with completely different values. Some people still work in calories, that may be why the values are so different. The ones on that page are kJ/mol.

Bear in mind that data like this is for a "typical" bond of its type, so don't be too suprised if there is a little variation from source to source.
My research: Google Scholar and Researchgate

Go to a science library not a public library.  ::)

You can find one on any local university campus.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Many colleges allow their students to access many online reference material over the internet using their library website and library card/numbers.

I would check your schools library page and look for something like that, because chances are pretty good you can have free access to the CRC HandBook of Chemistry & Physics.
