Question

32. Alkali metals react with oxygen or air to give: (A) acidic oxides (B) basic oxides (C) amphoteric oxides (D) none of the above




ANSWER ME AS USUAL AS POSSIBLE ​

Answer 1

Answer:

basic oxide

Explanation:

element with less electronegativity tends to form basic oxides.

Example..sodium

And sodium is also an alkali metal

Answer 2

Alkali metals react with oxygen or air to give basic oxides.

• Alkali metals are Li, Na, K, Rb, Cs and Fr.
• These metals react with oxygen or air to form metal oxide.
• By dissolving these metal oxides in the water we can get metal hydroxide.
• Now the metal hydroxide dissociates to give metal ion and hydroxyl ion and acts as a base.
• Hence alkali metals react with oxygen or air to give basic oxides.
• Hence the correct option is B.
