Question

Assertion (A) In a group while going from top to bottom, oxidising nature of element decreases.
Reason (R) The tendency to accept electrons decreases, on moving down the group.

• A. Both $A$ and $R$ are correct; $R$ is the correct explanation of $A$.
• B. Both $A$ and $R$ are correct; and $R$ is not the correct explanation of $A$.
• C. $A$ is correct; $R$ is incorrect.
• D. $R$ is correct; $A$ is incorrect.

Answer 1

Answer: (A)

In a group, metallic character increases and tendency to accept electrons decreases on moving down. As a result oxidising properties decreases.
Thus, both $A$ and $R$ are correct and $R$ is the correct explanation of $A$.
