Consider the following electronegativity values:
h = 2.1, cl = 3.0, f = 4.0
which molecule below would you expect to have the more polar bond?

a) hcl b) h2 c) hf d) cl2 e) f2

Given the electronegativity values, the molecule with the most polar bond is d) HF.

The polarity of a bond depends on the difference in the electronegativities of the elements that form it. The higher the difference in their electronegativities, the more polar the bond.

Let's calculate the difference in the electronegativities for the following molecules.

Given the electronegativity values, the molecule with the most polar bond is d) HF.

option C. HF

Explanation: A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. Fluorine is more electronegative than hydrogen so the electrons in the bond are more closely associated with the fluorine atom than with the hydrogen atom.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
