Question:
Which of the following elements does not form electron-deficient compounds?
Which of the following elements does not form electron-deficient compounds?
Show Hint
Compare the covalent character and bridging tendency of Li, Na, Be and Al.
Updated On: Jul 3, 2026
- Li
- Na
- Be
- Al
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Li forms electron-deficient alkyllithium clusters. Be forms BeCl2/BeH2 polymers. Al forms Al2Cl6 dimer.
Step 2: Na is highly ionic, no bridged covalent clusters.
