(Sample Problems 4.1 and 4.2)
4.1 What two factors cause water to be polar?
Interpretation: Two factors that cause polarity in
Concept introduction: Solution is made by two portions, solute, and solvent. Solute represents substance present in small quantity while solvent represents substance that dissolves solute.
Polarity in molecule is generated if it has unequal distributed electron density between bonds. Polar molecule has partial charges on atoms of the molecule. The general representation of polar molecule is as follows:
Here, B has high electronegative value than A.
Explanation of Solution
Water molecule has bend shape. In this shape, oxygen present as central atom and two hydrogen atoms are present as side atom. Structure of
Bond
