The normal boiling point of 2-propanol, (ch3)2choh, is 83 ºc, while that of acetone, (ch3)2c=o, is 56 ºc. what is the principal reason for the greater boiling point of 2- propanol?

Answer is: the greater boiling point of 2- propanol is because hydrogen bonds between 2-propanol molecules and more energy is required to breake those bonds.
Hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (H), covalently bound to a highly electronegative atom such as flourine (F), oxygen (O) and nitrogen (N) atoms.
