Group 2, or in the Alkaline Earth Metals section. This is due to the necessity to have a +2 charge to balance out or negate the -2 charge two Bromines carry.
Answer:
C-O
Explanation:
you have to check the all four bonds and find out their electronegativity difference. Whichever has the largest difference, is your answer.
- N-O = 3.04 - 3.44 = -0.4
- Cl-Cl = 3.16 -3.16 = 0
- C-O = 3.44 - 2.55 = 0.89
- C-H = 2.55 - 2.20= 0.35
Now check the differences, the largest electronegativity differences means the most polar bond
