Question

Assertion :S-Block elements do not occur free in nature. Reason: S-Block elements are highly electropositive in nature.

Choose the appropriate option from the following :

• A. Both assertion and reason are true and the reason is the correct explanation of the assertion.
• B. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
• C. Assertion is true but reason is false.
• D. Both assertion and reason are false statements.

Answer 1

The correct option is A Both assertion and reason are true and the reason is the correct explanation of the assertion.

The s-block elements are highly electropositive in nature. So, these are very reactive. That is why these elements do not occur free in nature.

Usually, the s-group elements occur in nature as halides, carbonates and sulphates, These metals are obtained from their molten halides by electrolytic reduction.

Hence, option $\left(A\right)$ is correct.
