Question

Match List-I with List-II 



Choose the correct answer from the options given below:

• (A) (I), (B) (III), (C) (IV), (D) (II)
• (A) (I), (B) (III), (C) (II), (D) (IV)
• (A) (I), (B) (II), (C) (IV), (D) (III)
• (A) (III), (B) (IV), (C) (I), (D) (II)

Hint:

Electronegativity decreases as you move down the alkali metals group.

Answer 1

The Correct Option is C

- Lithium (Li), denoted as (A), exhibits the highest electronegativity among the listed alkali metals, with a value of approximately 1.0.
- Sodium (Na), denoted as (B), has an electronegativity of 0.9.
- Potassium (K), denoted as (C), has an electronegativity of 0.8.
- Cesium (Cs), denoted as (D), possesses the lowest electronegativity among the elements presented, registering at 0.7.
Conclusion:
Therefore, the correct matching is: \[ \text{(A) (I), (B) (II), (C) (IV), (D) (III)} \]
Final Answer: \[ \boxed{\text{(A) (I), (B) (II), (C) (IV), (D) (III)}} \]
