Alcohol can increase your risk of cancer, but it can also prevent some heart attacks. Here's the complicated truth.

Electrons can be shared unequally in a molecule, creating a polar molecule. Opposite polar ends of molecules attract and hold one molecule to another. Alcohol has one O–H bond which is polar, but a ...

However, the solubility decreases as the length of the alcohol molecule gets longer, so butanol is less soluble than propanol. It may not mix easily, and two distinct layers might be left in the ...

The polar part of alcohol is attracted to and interacts with polar water molecules and causes alcohol to dissolve. The polar parts of the glucose molecule are attracted to and interact with water and ...
