Butanol polarity index

1-Butanol, also known as butan-1-ol or n-butanol, is a primary alcohol with the chemical formula C4H9OH and a linear structure. Isomers of 1-butanol are isobutanol, butan-2-ol and tert-butanol. The unmodified term butanol usually refers to the straight chain isomer. 1-Butanol occurs naturally as a minor product of the ethanol fermentation of sugars and other saccharides and is present in many foods and drinks.

WebMeasuring Polarity Bond dipole moment is the measure of the polarity of a chemical bond. It is measured in 0 to 11 debyes (D), with 0 indicating no dipole moment and 11 being strongly polar. For many substances, such as covalently bound liquids, it's useful to know the polarity of an entire molecule rather than its individual bonds.
