"Smart as a whip" does not appear in precisely this wording in the Oxford English Dictionary, or at least I wss unable to discover it. On the other hand the meaning it assigns to the adjective "smart" is: "I. †1. a. Of a whip, rod, etc.: Inflicting or causing pain; sharp, biting, stinging. Obs."
"Smart" in the meaning of causing pain or being the source of pain is very old, much older, for instance, than this line from an Elizabethan lute song:
"O, 'tis a crack to my back, 'tis a smart to my heart, and to my belly."
The meaning "painful as a whip" has been supplanted by "clever as a whip" because of the shift away from the original mening of smart, which is no longer used as an adjective. Or so I conjecture.
