Physical properties of alcohols Molecules are polar, in the O-H bond, O is δ - and H is δ + Molecules have attractive forces between the molecules called hydrogen bonds, not as strong as covalent bonds. • Higher boiling point than corresponding alkanes. • Hydrogen bonds form between alcohol and water  molecules therefore they are miscible / soluble.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
