Chains of carbon with just hydrogen bonded are very nonpolar, while the -OH group on alcohols are very polar. Mehtanol is just one carbon with an -OH group, so it is quite polar. Butanol, on the other hand, is a four carbon chain with an -OH group on the end carbon. The longer nonpolar carbon chain makes butanol less polar than methanol.
What else can I help you with?
Is hexane or methanol more polar?
Ethanol is polar, as the non-polar OH group still exerts enough force over the rest of the chain to make the entire hydrocarbon dissolve. This trend continues with alcohols with one carbon (methanol) two carbons (ethanol) three carbons (propanol) and four carbons (butanol). However, butanol is only polar when the OH functional group is attached to a secondary carbon (i.e. butan-2-ol) Hexane is always non-polar, as it is a symmetrical hydrocarbon (like most of them) which means that all forces cancel each other out. So ethanol is more polar than hexane.
Why when you mix the water with butanol it becomes insoluble?
When water and butanol are mixed, they form two distinct layers because butanol is less dense than water. Butanol is insoluble in water due to the difference in polarity - water is polar, while butanol is less polar. This difference in polarity prevents the two substances from mixing on a molecular level, leading to their separation in layers.
Is methanol more polar than acetone?
Yes, methanol is more polar than acetone because it has a higher dipole moment and stronger hydrogen bonding capabilities due to its hydroxyl group. Acetone is a less polar solvent compared to methanol.
Why is propanol better than butanol?
Propanol has a lower molecular weight than butanol, making it lighter and more volatile. This results in propanol evaporating more quickly and having better solubility in water. Additionally, propanol is often less expensive and more readily available compared to butanol.
What are the differences between butanol and ethanol in terms of their chemical properties and potential applications?
Butanol and ethanol are both alcohols, but they differ in their chemical properties and applications. Butanol has a longer carbon chain than ethanol, making it less polar and more hydrophobic. This means butanol is less soluble in water compared to ethanol. Butanol also has a higher boiling point and is more volatile than ethanol. In terms of applications, ethanol is commonly used as a fuel additive, solvent, and in alcoholic beverages, while butanol is used as a solvent, in the production of plastics, and as a biofuel.
Why does butanol heat water more than methanol?
Butanol is has less polarity than methanol

Is butyl polar or non-polar?
Butanol, being an alcohol, is slightly polar. The C-O-H bonds are responsible for that. O being more electronegative pulls electrons towards itself from C and H atoms. However, it is less polar than methanol or ethanol.

Why is methanol less volatile than petrol?
At a basic chemical level, methanol is less reactive than petrol due to polarity. Just like water tends to hold together in droplets, methanol, being an alcohol, has polar molecules which hold the substance together. Petrol, on the other hand, is nonpolar, and doesn't have that force holding it together.
What compound is more polar and soluble in water methane or methanol and why?
Acetonitrile is slightly more polar than methanol. This is due to the presence of the C-N triple bond in acetonitrile (CH3CN).
Why is methanol more polar than ethanol?
Methane is CH4 or H-CH3 Ethane is CH3-CH3 When compared to H- (in methane), the CH3- (methyl group in ethane) is more electron donating and hence ethane is more basic than methane.
Why is tri methyl methanol a weaker acid than methanol?
Trimethyl methanol is another name for t-butanol, so I will refer to it as such to avoid confusion. It's easier to think about this problem in terms of their conjugate bases. Methyl groups are more electron donating than hydrogen atoms. So in t-butoxide, the O- has more electron density than the O- in methoxide. More electron density means the t-butoxide "wants" a proton more. In other words, t-butanol "wants" to keep its proton more than methanol does. This makes t-butanol a weaker acid (with a higher pKa), since the stronger acid is the one that loses its proton more readily.
Is methanol more soluable than methane?
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.
