Question

use the figure provided to determine which of the following has bonds with the greatest bond - polarity? select the correct answer below: hcl no₂ nh₃ h₂o

Explanation:

Step1: Recall bond - polarity concept

Bond polarity depends on electronegativity difference.

Step2: Identify electronegativities

Electronegativity values: H = 2.2, Cl = 3.16, N = 3.04, O = 3.44.

Step3: Calculate electronegativity differences

For H - Cl: $3.16 - 2.2=0.96$.
For N - O in NO₂: $3.44 - 3.04 = 0.4$.
For N - H in NH₃: $3.04 - 2.2 = 0.84$.
For H - O in H₂O: $3.44 - 2.2=1.24$.

Step4: Compare differences

1.24 (H - O in H₂O) is the largest. So H₂O has the greatest bond - polarity.

Answer:

H₂O
