Question

which of the following bonds exhibits the greatest difference in electronegativity?
h-se
h-h
h-cl
h-ge

Explanation:

Step1: List electronegativity values

Electronegativity (Pauling scale): H=2.20, Se=2.55, Cl=3.16, Ge=2.01

Step2: Calculate electronegativity differences

• H-Se: $|2.20 - 2.55| = 0.35$
• H-H: $|2.20 - 2.20| = 0$
• H-Cl: $|2.20 - 3.16| = 0.96$
• H-Ge: $|2.20 - 2.01| = 0.19$

Step3: Compare the calculated values

0.96 > 0.35 > 0.19 > 0

Answer:

H-Cl
