Document Summary

Tutorial starts again next week: beta elimination reactions. C-lg can undergo elimination reaction in addition to the substitution reactions already discussed. Strong nucleophile base running around looking for a c+ Now looking at a molecule that has both a c+ and a hydrogen that runs into either one of them or both of them that"s what give s you a beta elimination reaction. Leaving groups are always delta minus and the carbon is a delta plus. Because the h atom and the lg group come off c atoms that are adjacent (often labeled alpha and beta) this reaction is called a b elimination) In many cases elimination reactions and substitution reactions occur together. All species considered earlier as nucleophiles can also act as bases- the only difference is whether the species attacks a carbon or a base: the only difference is where it comes into the molecule.
