Answer:
So the correct answer is e) O-H
Explanation:
To determine the most polar bond we calculate the electronegativity difference in each bond and determine the highest value:
a) N-H = 3.0 - 2.1 = 0.9
b) O-C = 3.5 - 2.5 = 1
c) O-N = 3.5 - 3 = 0.5
d) C-H = 2.5 - 2.1 = 0.4
e) O-H = 3.5 - 2.1 = 1.4
So the correct answer is e) O-H
