43. Tertiary alcohols with two identical alkyl groups attached
to the alcohol carbon can be made either from an ester and two
moles of a Grignard reagent, or from a ketone and one mole of a
Grignard reagent. Use retrosynthetic analysis to suggest one path
of each type to synthesize 1,1-diphenylethanol. (Click and drag the

EXTRA CREDIT: There are three commonly encountered reactive carbon intermediates: radicals, sarbocations, and carbanions. But there is a fourth intermediate, called a carbene, which shows up occasionally in reactions. A carbene has two bonds and a lone pair on carbon, but nothing else. For instance, ChC: is called dichlorocarbene and is an intermediate in the following reaction. Provide the mechanism, the reaction coordinate diagram, and the rate law for this reaction.
