Document Summary
Carboxyl group present in carboxylic acids, amides, esters, anhydrides & acid. Aldehyde: carbonyl at the end of the chain. Ketone: carbonyl in the middle of the chain. Carboxyl: has oh attached to c=o carbon. Carbonyl: c=o without an oh attached to carbon. Amine: nh 2 bound to r group.

Heat can be used to determine at which. G = 0 temperature a nonspontaneous reaction becomes spontaneous; equation becomes: , can be used to determine entropy change that occurs in a phase change e. g. h 2 o (s) h 2 o (l)
