This is an example of an aldol condensation between an acetone anion and
acetaldehyde. Note the mechanism proceeds through addition of an anion to an
aldehyde carbonyl. Arrow pushing is illustrated below:
This is an example of the first step in the acid-mediated solvolysis of a tertiary
alcohol. Note that protonation of the alcohol occurs under strongly acidic con-
ditions with electrons moving toward the positive charge residing on the proton.
Arrow pushing is illustrated below:
This is an example of the second step in the acid-mediated solvolysis of a tertiary
alcohol. Note that the protonated alcohol separates as water and leaves the positive
charge on the carbon atom. For clarity, the bond was lengthened to allow space for
the arrow. Note that the electrons in the bond move toward the positive charge
residing on the oxygen. Arrow pushing is illustrated below:
