Which of the following compounds has the highest electronegativity difference?

Step 1: Understand what electronegativity means. It is a measure of how strongly an atom attracts electrons in a bond.
Step 2: Identify the electronegativity values of the elements involved. For sodium (Na), the electronegativity is about 0.93, and for chlorine (Cl), it is about 3.16.
Step 3: Calculate the electronegativity difference by subtracting the smaller value from the larger value. So, 3.16 (Cl) - 0.93 (Na) = 2.23.
Step 4: Compare this difference with other compounds if provided. If no other compounds are given, conclude that NaCl has the highest difference.
