Document Summary

Electrophile al, b, - has empty orbitals: cations c with positive charge. Allow starts at a place of electron abundance and end where there is lack of electrons. If oxygen has a positive charge it can not give away electrons so it cant be a nucleophile. If methyl is attached to a less electronegative atom it"s a nucleophile. If methyl is attached to a more electronegative atom it"s an electrophile. Double bons makes a molecule a nucleophile. Does not matter which carbon is having a positive charge. Carbon with positive charge doesn"t have an octet making it very unstable so bromine will be sharing its electrons with carbons. Do the assigned reading for slides 45 - 57. Delta g = delta h t ( dalta s) entropy is disorder: more reagent to less reagent means less molecules interacting with each other => less disorder => entropy is negative number. 2 mole of reactant > 1 mole of reactant.
