Compounds which tend to donate electron pair are known as lewis bases or nucleophile. Which one of the following is not a Lewis base?
Correct answer: C. AlCl3
- A. CH3-NH2
- B. PH3
- C. AlCl3
- D. H2O
Explanation
AlCl3 is Lewis acid which can accept electron pair so it cannot be Lewis base but it is Lewis acid.

About Acids, Bases and Salts
Acid and base behaviour is explained through the Bronsted-Lowry transfer of protons and the Lewis donation or acceptance of electron pairs. The topic includes pH, pOH, ionisation and water equilibrium, plus salt formation and hydrolysis, where a salt solution may become acidic, basic or neutral.
