Answer:
Isopropanol>dichloromethane>1-butene>propane
Explanation:
Stronger intermolecular forces usually correlate with higher boiling points
Boiling points generally increases with molecular weight due to increased strength of dispersion forces
Hydrocarbons exhibit only dispersion forces.
For the arrangement of compounds above, isopropanol has the highest boiling point because it forms hydrogen bonds with water. Dichloromethane possess dipole-dipole interaction which accounts for its higher boiling point. 1-butene has a higher boiling point than propane because it has higher molecular mass thus greater dispersion forces.

Answer:</h3>
Molarity is 0.046 M
<h3>
Explanation:</h3>
We are given;
1.72 mol of LiCl in 37.5 L of solution
We will take the question to be; calculate the molarity of LiCl
Therefore,
we can start by defining molarity as the concentration of a solution in moles per liter.
Molarity of a solution is calculated by dividing the number of moles of solute by the volume of solution.
Molarity = Moles of solute ÷ Volume of the solution
Thus, in this case;
Molarity of LiCl = Moles of LiCl ÷ Volume of the solution
= 1.72 moles ÷ 37.5 L
= 0.0459 M
= 0.046 M
Therefore, the molarity of LiCl solution is 0.046 M
Electron because of the charge it has
