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.

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.
Is methanol more polar than acetone?
Methanol is more polar because is capable of dipole-dipole interactions AND hydrogen bonding while acetone is capable of just dipole-dipole interaction.
Why is propanol better than butanol?
You have to look at the molecular bonding of the two and the energy that can be released through bonds broken. Butanol releases a lot more energy when the bonds between the atoms in butanol are broken because there are more bonds to break. There are four carbons in butanol, with atomic formula CH3CH2CH2CH2OH, versus only one carbon in methanol, with formula CH3OH. There is simply more energy in butanol than in methanol. Look up molecular bonding energy for more information and an imperial answer.
Why does 1 butanol have a higher boiling point then diethyl ether?
Diethyl ether, and 1-butanol are similar in size (number of electrons), therefore, their boiling points will be determined by polarity. Diethyl ether has two polar C-O bonds. 1-butanol also has two polar bonds (C-O and O-H), but the O-H bond is more polar than the C-O bond, making 1-butanol more polar than diethyl ether and giving it a higher boiling point. Diethyl ether has weaker intermolecular forces of attraction and therefore a lower boiling point.
Which is more polar methanol or acetonitrile and why?
Acetonitrile is a more polar molecule than methanol because of the triple bond and lone pair on the nitrogen (N) atom in acetonitrile. This makes that end of the molecule highly electronegative, even more so than an oxygen (O) atom containing two lone pairs in methanol.
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.
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.

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.
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.
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).
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.
Difference between methanol and ethanol?
Methanol is CH3OH, ethanol is CH3CH2OH. Both are alcohols, ethanol has one carbon more (or a CH2 group more) and is less polar than methanol. Also ethanol has higher boiling point than methanol.
Why does 1-butanol have a higher boiling point then diethyl ether?
Diethyl ether, and 1-butanol are similar in size (number of electrons), therefore, their boiling points will be determined by polarity. Diethyl ether has two polar C-O bonds. 1-butanol also has two polar bonds (C-O and O-H), but the O-H bond is more polar than the C-O bond, making 1-butanol more polar than diethyl ether and giving it a higher boiling point. Diethyl ether has weaker intermolecular forces of attraction and therefore a lower boiling point.
