Question

Assertion (A): Hydrogen resembles alkali metals
Reason (R): Hydrogen exists in atomic form at extreme temperatures (~5000K) Choose the most appropriate of the following:

• A. Both the Assertion and the Reason are correct and the latter explains the former
• B. Both the Assertion and the Reason are correct but the latter does not explain the former
• C. Assertion is true but the Reason is false
• D. Assertion is false while the Reason is true

Answer 1

The correct option is B

Both the Assertion and the Reason are correct but the latter does not explain the former

The Assertion is correct: Both alkali metals and Hydrogen tend to form cations. They are both good reducing agents. Both alkali metals and Hydrogen react with Halogens, although the nature of halides is very different.

As a separate statement, Reason is also correct. Atomic Hydrogen can be isolated at extreme temperature. But this does not explain the Assertion
