Question

Be and Al resemble in the following but not in :

• A. both form electron decient hydrides
• B. both are rendered passive by $HN{O}_3$
• C. both form amphoteric oxides
• D. both have sp-hybridisation in their compounds

Answer 1

The correct option is D both have sp-hybridisation in their compounds

Both form electron deficient hydrides due to incomplete octet.

Both form amphoteric oxides as their oxides react with both acid and base.

Be have sp-hybridization and Al have sp${}^2$- hybridization in their compounds.
