Q. Given below are two statements : Statement (I) : An element in the extreme left of the periodic table forms acidic oxides. Statement (II) : Acid is formed during the reaction between water and oxide of a reactive element present in the extreme right of the periodic table. In the light of the above statements, choose the correct answer from the options given below :
A) Statement I is true but Statement II is false
B) Both Statement I and Statement II are true
C) Both Statement I and Statement II are false
D) Statement I is false but Statement II is true
Explanation
[Solution by Dr. Abubacker] Elements at the extreme left (alkali metals) form basic oxides, so Statement I is false. Oxides of reactive non-metals on the extreme right (e.g. Cl₂O₇, Cl₂O) react with water to give acids (HClO₄, HOCl), so Statement II is true. Answer (4).
