Question

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

Answer 1

Correct Answer - Option 4 : C

Concept:

• Carbon (C) has greatest ability to form stable pπ – pπ multiple bonds. 2p-orbitals of this element participate in the process.
• The stability of multiple bonds of C is attributed to their closeness with C-nucleus.
• Thus, the smaller size of C plays a significant role in the process.
