NEET levelSingle correct optionDifficulty 1 of 3o4148

Potassium tert-butoxide, , favours elimination over substitution with alkyl halides mainly because it is

  1. Aa weak base but a good nucleophile
  2. Ba strong acid
  3. Ca strong base but a poor nucleophile due to steric bulk
  4. Dinsoluble in all organic solvents

Answer: C

The bulky tert-butyl group hinders attack at carbon (SN2) but does not prevent removal of an exposed beta-hydrogen, so it acts as a base rather than a nucleophile.
