The element that shows greater ability to form pπ - pπ multiple bonds is:

The element that shows greater ability to form pπ-pπ multiple bonds is:
  1. Sn
  2. C
  3. Si
  4. Ge

Solution

C forms most stable pπ-pπ bonds because it has high bond dissociation energy, more electronegativity, high ionization energy and vacant d- orbital is unavailable. While others have vacant orbital and low bond dissociation enthalpy and low ionisation enthalpy
