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

- Li (A) has the highest electronegativity in the alkali metals, approximately 1.0.
- Na (B) has an electronegativity of 0.9.
- K (C) has an electronegativity of 0.8.
- Cs (D) has the lowest electronegativity of these elements, 0.7.
Conclusion:
Thus, the correct answer is: \[ \text{(A) (I), (B) (II), (C) (IV), (D) (III)} \]
Final Answer: \[ \boxed{\text{(A) (I), (B) (II), (C) (IV), (D) (III)}} \]
