Select the correct statement (s)....

Select the correct statement `(s)`.

A

Mulliken's values of `EN` are about `2.8` times more than the Pauling scale.

B

Mulliken's value of `EN` are about `2.8` times less than the Pauling scale.

C

On Mulliken's scale if `IP` and `EA` are in `kJ mol^(-1)`, then `EN = (IP + EN)/(540)`

D

On Mulliken's scale if `IP` and `EA` are in kcal `mol^(-1)`, then `EN = (IP+EA)/(2 xx 62.5)`

The correct Answer is:
To solve the question regarding the correctness of the statements related to Mulliken and Pauling scales of electronegativity, we can follow these steps: ### Step 1: Understand the Mulliken and Pauling scales - The Mulliken scale of electronegativity is based on the average of the ionization energy (I.P) and electron affinity (E.A) of an element. - The Pauling scale is a different method of measuring electronegativity. ### Step 2: Analyze the first statement - The first statement claims that the Mulliken value of electronegativity is around 2.8 times more than the Pauling scale. - According to the information provided in the video transcript, this statement is correct because it states that Mulliken electronegativity is equal to 2.8 times the Pauling electronegativity. ### Step 3: Analyze the second statement - The second statement claims that the Mulliken value of electronegativity is 2.8 times less than the Pauling scale. - This statement is incorrect as it contradicts the first statement. The Mulliken value is actually more than the Pauling scale, not less. ### Step 4: Analyze the third statement - The third statement provides a formula for calculating Mulliken electronegativity when ionization potential and electron affinity are in kilojoules. - The formula given is E_n = (I.P + E.A) / 540, which is indeed correct as per the information in the transcript. ### Step 5: Analyze the fourth statement - The fourth statement mentions a formula for calculating Mulliken electronegativity in kilocalories, which is E_n = (I.P + E.A) / 125. - This statement is also correct as per the information provided in the transcript. ### Conclusion Based on the analysis: - The correct statements are A (first statement), C (third statement), and D (fourth statement). - The incorrect statement is B (second statement). ### Final Answer The correct statements are A, C, and D. ---
