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?

2-Propanol has higher boiling point than acetone due to the inter-molecular hydrogen bond formation of 2-propanol which increase the intermolecular forces between molecules and leads to higher boiling point in propanol while in case of acetone the intermolecular present between molecules are dipole-dipole interaction which has smaller effect when compared to hydrogen bond
