Question

An oxide of an element is a gas and dissolves in water to give an acidic solution. The element belongs to:

• A. II A group
• B. IV A group
• C. VIII group
• D. Zero group

Answer 1

Answer: (B)

IV A group

Oxides of 2A (beryllium) group are basic in nature and thus their aqueous solutions are basic. Oxides of 4A(carbon) group are acidic in nature and their aqueous solution are thus acidic.VIII group does not form any oxides. Their is no zero group.
