Pentane is not soluable because it is non-polar & water is polar. As for isopropyl alcohol, the atoms of the OH group form hydrogen bonds with the H & O atoms of water, thereby allowing solubility.
Even though pentanol is polar, thereby being soluble in water, it's solubility is limited due to the fact that its polarity is relatively low compared to methanol (CH3OH). The polarity comes from the -OH group, which is not the majority of the molecule making it less soluble than methanol, ethanol, propanol, and butanol in which the -OH group makes up more of the molecule.
Both are polar molecules because of their OH functional groups, so both can hydrogen bond with water with that OH group. Given this, the nonpolar portion of propanol is much smaller than the nonpolar portion of hexanol in relation to their polar parts (propanol has just 3 carbons to hexanol's 6 carbons).
The boiling point depends on the intermolecular forces acting on the molecules. Water has hydrogen bonding, which is one of the strongest molecular forces. Pentane exhibits fairly weak bonding, which means it takes less energy to create a phase change.
Yes, methanol is more soluble than pentanol. The reason is that although both alcohols have an OH group that is attracted to water, pentanol has a 5-carbon, non-polar (hydrophobic) chain that significantly decreases its solubility. The solubilty decreases as the carbon chain increases. I hope this helps.
What is the difference between 2-pentanol from 3-pentanol?
A fertilizer for agriculture must be soluble in water, more or less.
No. You have it the wrong way. Salt is more soluble in hot water than in cold water.
Many alcohols are soluble in water because of the -OH group that they all contain. This is the polar part of the molecule which makes it polar and thus soluble in water. The part of the molecule that limits the solubility in water is the carbon chain attached to this -OH group. The longer and more branched the carbon chain, the less soluble it is in water.
The OH group makes it slightly water soluble while the carbon group resists solubility. The 3-pentanol molecule is slightly water soluble.
"Alcohols, ethers and epoxides having less than or 5 carbon atoms are water soluble because they each have an oxygen atom capable of hydrogen bonding." "Alcohols, ethers and epoxides having more than 5 carbon atoms are insoluble because the non-polar alkyl portion is too large to dissolve in water" Source: Organic chemistry (second edition) by Janice Gorzynski Smith
Yes it is soluble.
Not so much. As alcohols get bigger they tend to be less and less soluble in water. Methanol, ethanol, and propanol are pretty much fully miscible in water at room temperature. By the time you get to 1-butanol, the difficulty in jamming the non-polar end of the molecule between water molecules that want to interact with each other starts to make the molecule only partially soluble (somewhere around 7-8 grams per 100 mL of water). 1-pentanol is even worse, with a solubility coming in around 2-3 grams per 100 mL.

Sugars with increasing carbon units tends to be less soluble in water like polysaccharides.
Butanal is more soluble in water because it has less carbons attached. The more carbons you add to a molecule the less soluble it becomes
I think oil will be less soluble in water at elevated temperatures.
Lithium flouride is less soluble because the hydration enthalpy of lithiumflouride is less
