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.
completely insoluble in water. soluble in 0.1N sodium hydroxide solution.
Soluble in acetone, dimethyl formamide, DMSO, dichloromethane, 100% ethanol or methanol; sparingly soluble in water.
Octanol is more soluble in hexane because it has a longer nonpolar hydrocarbon chain.
Butanol is has less polarity than methanol
Yes, methanol is CH3OH and methane is CH4. Methanol is polar (because of the O-H bond) and methane is non-polar (because it is a hydrocarbon.) Water (which is polar) will dissolve other polar things, but not non-polar things.
Yes, sodium is more soluble in water than methanol. Sodium is a metal that reacts violently with water, producing sodium hydroxide and hydrogen gas. Methanol is a polar molecule that can form hydrogen bonds with water, but it is not as soluble as sodium.
Ethanol is more soluble in water than methanol because ethanol has a longer hydrocarbon chain which increases its ability to hydrogen bond with water molecules, making it more soluble. Methanol has a shorter hydrocarbon chain which reduces its ability to hydrogen bond with water molecules, decreasing its solubility.
Acetonitrile is slightly more polar than methanol. This is due to the presence of the C-N triple bond in acetonitrile (CH3CN).
yes
Tetraphenylcyclopentadienone is not very soluble in methanol due to its non-polar nature and the methanol being more polar. However, small amounts may dissolve due to partial solubility.
completely insoluble in water. soluble in 0.1N sodium hydroxide solution.
Methanol is more polar than ethanol because it has a smaller carbon backbone and is completely soluble in water due to the presence of the hydroxyl group. This makes methanol more likely to interact with water molecules through hydrogen bonding, which increases its polarity compared to ethanol.
No, water is heavier than methanol. Water has a higher density compared to methanol, which means that for the same volume, water will weigh more than methanol.
Soluble in acetone, dimethyl formamide, DMSO, dichloromethane, 100% ethanol or methanol; sparingly soluble in water.
The specific gravity of a methanol-water mixture depends on the ratio of methanol to water. Generally, a mixture with more methanol will have a lower specific gravity than pure water.
Octanol is more soluble in hexane because it has a longer nonpolar hydrocarbon chain.
The best solvent for boric acid is water, as boric acid is highly soluble in water. It can also dissolve in alcohol, but water is more commonly used due to its effectiveness and availability.
