What is the difference between butanol and n-butanol?
The unmodified term butanol usually refers to the straight chain isomer with the alcohol functional group at the terminal carbon, which is also known as n-butanol or 1-butanol. The straight chain isomer with the alcohol at an internal carbon is sec-butanol or 2-butanol.
Is n-butanol hydrophobic?
The alcohol is a hydrophilic component due to the ability to hydrogen bond with the water. The alkyl chain is a hydrophobic component. The 1-butanol has the least water solubility due to the larger surface area of the hydrophobic component.
Is butanol denser than water?
Sec-butyl alcohol appears as a clear colorless liquid with an alcohol odor. Flash point below 0° F. Less dense than water.

Is n-Butanol soluble in water?
partial miscibility in water …the solubility (weight percent) of n-butyl alcohol in water is 6.5 percent, whereas that of water in n-butyl alcohol is 22.4 percent.
Is n-Butanol polar or nonpolar?
You will see that n-butanol is not very polar (in the sense of dipolar bonding), but that it is higly capable of hydrogen bonding; while ethyl acetate is about the same polarity, but poorer in terms of hydrogen bonding.
Is N-butanol soluble in water?
Does butanol mix with water?
n-Butanol is soluble in water. It is a polar molecule unlike what others have suggested. It’s not as soluble as shorter chain alcohols such as methanol. The polar part is the -OH group whilst the non polar part is the greasy hydrocarbon chain.
Is n-Butanol miscibility with water?
n-Butanol (1-butanol) is partially miscible with water so it cannot dissolve all the water fraction. Of the alcohol isomers, (having the formula C4H9-OH), the only compound which is totally miscible with water is tertiary-butanol or 2-methyl-2-propanol.
Is n-Butanol miscible in water?
n-Butanol only has limited miscibility in water, however it is easily soluble in regular solvents such as ethers, alcohol, glycols and hydrocarbons. This solvent is very flammable, with a flashpoint of around 35° C.
