The Wittig reaction involves coupling between a phosphonium ylide and a carbonyl-containing molecule. If a chemist wants to use the Wittig reaction to synthesize 2-methyl-2-butene, which reactants should be used?
Carbonyl Compound %u2013 Option 1) 2-butanone Option 2) 2-ethanone
Phosphonium Ylide %u2013 Option 1) (C6H5)3P=CHCH3 Option 2) (C6H5)3P=CHCH2CH3
Choose only one option of carbonyl and phosphonium.
