Question

based on the periodic table of electronegativity in the slides, which of the following bonds would be the most polar? a. a bond between oxygen (o) and oxygen (o). b. a bond between hydrogen (h) and oxygen (o). c. a bond between nitrogen (n) and hydrogen (h). d. a bond between hydrogen (h) and carbon (c).

Explanation:

Step1: Recall polarity concept

Polarity of a bond depends on electronegativity difference.

Step2: Determine electronegativity values

Electronegativity values: H = 2.2, C = 2.5, N = 3.04, O = 3.44.

Step3: Calculate differences

For O - O: $|3.44 - 3.44|=0$; for H - O: $|2.2 - 3.44| = 1.24$; for N - H: $|3.04 - 2.2|=0.84$; for H - C: $|2.2 - 2.5| = 0.3$.

Step4: Compare differences

1.24 (H - O) > 0.84 (N - H) > 0.3 (H - C) > 0 (O - O).

Answer:

B. A bond between Hydrogen (H) and Oxygen (O)
