Question

Use the chart to determine which pairs of atoms are arranged in the correct order according to increasing bond polarity?

H – Cl < H – F < H – O < H – S

H – S < H – Cl < H – O < H – F

H – O < H – S < H – Cl < H – F

H – F < H – O < H – Cl < H – S

Answer 1

Elements
Electronegativity
aluminum (Al) 1.61
calcium (Ca) 1
carbon (C) 2.55
chlorine (Cl) 3.16
fluorine (F) 4
hydrogen (H) 2.2
iron (Fe) 1.83
nitrogen (N) 3.04
oxygen (O) 3.44
phosphorus (P) 2.19
potassium (K) 0.82
silicon (Si) 1.9
sulfur (S) 2.58

Answer 2

for each bond, look up the electronegativity for each element

then subtract them

then order them from smallest to largest

Answer 3

example:

Answer 4

H - Cl

H = 2.2, Cl = 3.16

so the difference is 1.04

Answer 5

we would then repeat this process for all the bonds and organize them in ascending order
