Answer: 1. 1-propanol can form hydrogen bonds with water, but butane cannot.
2. 1-propanol is more soluble than ethyl methyl ether because it can form more hydrogen bonds with water.
3. Ethanol is more soluble in water than 1-hexanol because it has a shorter carbon chain.
Step-by-step explanation:
It is know that like dissolves like. That is polar substance will be soluble in polar solvent and non-polar substance will be soluble in non-polar solvent.
As 1-propanol is polar in nature due to the alcoholic group present in it so, it is able to form hydrogen bonds with water. Hence, it readily dissolves in water. Whereas butane is non-polar in nature and it will not dissolve in water (polar solvent).
Also, smaller is the number of carbon chain present in a compound smaller will be its surface area. Hence, more readily it will dissolve in water.
For example, ethanol has less number of carbon atoms than 1-hexanol. So, ethanol will be more soluble in water than 1-hexanol.
Thus, we can conclude that given blanks are filled as follows.
1. 1-propanol can form hydrogen bonds with water, but butane cannot.
2. 1-propanol is more soluble than ethyl methyl ether because it can form more hydrogen bonds with water.
3. Ethanol is more soluble in water than 1-hexanol because it has a shorter carbon chain.
