# Problem: Explain why 1-propanol (CH3CH2CH2OH) is miscible in both water (H2O) and hexane (C6H6) when hexane and water are barely soluble in each other.

###### FREE Expert Solution

We’re being asked why 1-propanol is miscible with water and hexane while hexane is not miscible with water

The problem can be separated into three statements:

• 1-propanol is miscible with hexane
• 1-propanol is miscible with water
• hexane is not miscible with water

This problem talks about the miscibility of the compounds.

miscible → they will mix and will form a homogeneous mixture
immiscible → they will not mix and will form a heterogeneous mixture

We’re going to use the theory “likes” dissolving “likes”  which states that the solvent can only completely dissolve the solute if they share similar polarity
