Question

multiple choice 1 point which of the following has the greatest electronegativity difference between the bonded atoms? kbr co f2 hcl

Explanation:

Step1: Recall electronegativity values

Electronegativity values from the Pauling scale are used. K (0.82), Br (2.96), C (2.55), O (3.44), F (3.98), H (2.20), Cl (3.16).

Step2: Calculate electronegativity differences for each compound

For KBr: $|2.96 - 0.82|=2.14$. For CO: $|3.44 - 2.55| = 0.89$. For $F_2$: $|3.98-3.98|=0$. For HCl: $|3.16 - 2.20|=0.96$.

Answer:

KBr
