Question

compared to (CH3)3N andCH3CH2---OH CH3CH2---OH will have hydrogen bondsbetween molecules. Why? what is the easiest way to see if a substance has ahydrogen bond 2-Which response includes all of the following substances inwhich london forces are the most significant factors in determiningboiling points and no other substances? CL2, HF, NE, KNO2 ,CCL4 compared to (CH3)3N andCH3CH2---OH CH3CH2---OH will have hydrogen bondsbetween molecules.

Explanation / Answer

Easiest way to tell hydrogen bonding: See O-H (i.e. H2O), N-H (i.e. NH3), or F-H (i.e. HF). The wording in the second question is confusing, but hopefully thiswill help you. Cl2: diatomic molecule, nonpolar, only london forces HF: hydrogen bonding, polar NE: noble gas, only london forces KNO2: metal is included - ionic bond CCl4: nonpolar, only london forces.
