Which of the following is most polar bond:a)S–Clb)Se–Clc)S...
Cl is more electronegative than Br and Se is less electronegative than S
So Se-Cl bond has most electronegativity difference and hence is most polar.
So Se-Cl bond has most electronegativity difference and hence is most polar.

Which of the following is most polar bond:a)S–Clb)Se–Clc)S...
Explanation:
Polarity of a bond depends on the difference in electronegativity between the two atoms that are involved in the bond. The greater the difference in electronegativity, the more polar the bond will be.
Electronegativity values for the given elements are:
- Sulfur (S) - 2.58
- Chlorine (Cl) - 3.16
- Bromine (Br) - 2.96
- Selenium (Se) - 2.55
To determine the most polar bond, we need to calculate the difference in electronegativity for each of the given compounds.
a) SCl: 3.16 - 2.58 = 0.58
b) SeCl: 3.16 - 2.55 = 0.61
c) SBr: 2.96 - 2.58 = 0.38
d) SeBr: 2.96 - 2.55 = 0.41
As we can see, the highest difference in electronegativity is for SeCl, making it the most polar bond among the given compounds.
Therefore, the correct answer is option B - SeCl.
