b. Explain the sequence of steps by which this reaction happens. c. A typical reaction involving a ketone (C=O) is the addition of a carbanion (like a Grignard reagent) to give an alcohol. Draw the mechanism for that reaction using 2-propanone as the ketone. d. Explain the sequence of steps by which this reaction happens. e. Note the first step in the 2-methylpropene reaction is addition of an electrophile H) at an sp2 hybridized carbon, and the first step in the 2-propanone reaction is the addition of the nucleophile at an sp2 hybridized carbon. Why are these reactions different when both carbons are s2 hybridized and are part of double bonds
