Question:
Which of the following statement(s) is (are) incorrect for alkali metals?
Which of the following statement(s) is (are) incorrect for alkali metals?
Show Hint
Check periodic trend and special Li behaviour first.
Updated On: Jan 9, 2026
- Li$^+$ is exceptionally small and shows covalent character in some compounds
- Sodium oxide is isomorphic in nature
- Lithium is strongest reducing agent
- All alkali metals give blue coloration in liquid ammonia
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Statement checks:
- (A) true due to high polarizing power.
- (C) true: high hydration energy.
- (D) true: ammoniated electron.
Step 2: (B) isomorphic word misused; Na$_2$O is amphoteric not isomorphic → wrong. Hence → (B).
Step 2: (B) isomorphic word misused; Na$_2$O is amphoteric not isomorphic → wrong. Hence → (B).
