i) A
ii) B
iii) C
iv) D

Answer 1

Answer:

Answer:

c

Explanation:

as C has atomic number 17 it is chlorine and other all are metals and chlorine is a non metal and oxides of non metal are acidic in nature

Answer 2

Answer:

iii) C

Explanation:

Elements B and C belong to the same period in a periodic table where C lies right of B. We know that moving left to right along the period increases non-metallic character and hence, the acidic character of the oxide. So, among B and C, C will form most likely to form an acidic oxide.
