Answer:
The answer is given below
Explanation:
When electronegativity difference arises between the bonded atoms, then a molecule is polar.
When electros are shared equally between the bonded atoms or when the polar bonds in a bigger molecule cancels out each other, then a a molucule is non polar.
(a) 50% isopropanol/H2O,--- 2 (second least polar)
(b) 25% isopropanol/H2O,----- 3 (third least polar)
(c) pure water----- is 4 (most polar)
(d) 70% isopropanol/H2O. 1 (least polar)
The following are the ranking of solution from the least polar to most polar.
70% isopropanol/H2O.
50% isopropanol/H2O
25% isopropanol/H2O
pure water
What is a Polar substance?
A Polar substance is a chemical substance whose atoms are bonded together by covalent bond. There is unequal sharing of electrons in polar substance. Example of polar substance is water.
Nonpolar substance refer to substance where there is unequal sharing of electrons.
Therefore, The following are the ranking of solution from the least polar to most polar.
70% isopropanol/H2O.
50% isopropanol/H2O
25% isopropanol/H2O
pure water.
