They burn in oxygen to give oxides at high temperature
Their halides are Lewis acids
They combine with nitrogen to form nitrides
They react with HCl to form chlorides
They burn in oxygen to give oxides at high temperature
Their halides are Lewis acids
Options
- A1, 4
- B3, 4
- C1, 3, 4
- D1, 2, 3, 4
Correct answer
C. 1, 3, 4
Step-by-step solution
Both B and Al can react with nitrogen to form nitride as follows
Boron is not attacked by HCl; while Al reacts with HCl to from and .
Both B and Al can react with oxygen to form their oxides.
Halides of both are electron deficient molecule, so they act as Lewis acids.
