What is the difference between a primary, secondary and tertiary alcohol ?

Explain what allows alcohols to be water soluble and why they have such high boiling and melting points ?
|
The highly electronegative polar bond between oxygen and hydrogen allow the strong intermolecular force called hydrogen bonds to form between the molecules of the alcohol. This is responsible for its high melting and boiling points. The fact that it is water soluble is because it is consequently a polar molecule.
