Question

question 6 (10 points) in which of these pairs of atoms would the bond be the least polar (i.e., lowest percent ionic character)? a) c - c b) o - c c) n - c d) c - h e) c - cl

Explanation:

Step1: Recall electronegativity values

Electronegativity values: \( C = 2.55\), \( H=2.20\), \( N = 3.04\), \( O=3.44\), \( Cl = 3.16\).

Step2: Calculate electronegativity differences

• For \( C - C\): \(\vert2.55 - 2.55\vert=0\)
• For \( O - C\): \(\vert3.44 - 2.55\vert = 0.89\)
• For \( N - C\): \(\vert3.04 - 2.55\vert=0.49\)
• For \( C - H\): \(\vert2.55 - 2.20\vert = 0.35\)
• For \( C - Cl\): \(\vert3.16 - 2.55\vert=0.61\)

Answer:

A. \( C - C\)
