Q.
Given below are two statements : [2025]

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 :

1 Both Statement I and Statement II are false

2 Both Statement I and Statement II are true

3 Statement I is true but Statement II is false

4 Statement I is false but Statement II is true

Ans.
(4)

Extreme left side of periodic table ( $s$ -block) has metals which form basic oxides. Acidic oxides (i.e.oxides which form acid upon reaction with water, e.g. ${CO}_{2} + H_{2} O \to H_{2} {CO}_{3}$ ) are formed by non-metals. Non-metals occupy extreme right side of periodic table.

Solution

1 Both Statement I and Statement II are false

2 Both Statement I and Statement II are true

3 Statement I is true but Statement II is false

4 Statement I is false but Statement II is true

Solution

1 Both Statement I and Statement II are false

2 Both Statement I and Statement II are true

3 Statement I is true but Statement II is false

4 Statement I is false but Statement II is true

Ans. (4) Extreme left side of periodic table (s-block) has metals which form basic oxides. Acidic oxides (i.e.oxides which form acid upon reaction with water, e.g. CO2+H2O→H2CO3) are formed by non-metals. Non-metals occupy extreme right side of periodic table.
