<p>in the just released ap chem frqs, they stated that the normal boiling point of Cl2 is higher than that of HCl, but I did some research just to confirm what I believed, and the normal boiling point of HCL is higher than that of Cl2, so has anyone contaced CB yet, or am I just hallucinating this whole question thing.</p>
<p>^^ I asked my teacher about this one. He said it was right. HCI has London Dispersion and Dipole Dipole, Cl2 has only London Dispersion. HOWEVER, since the molar mass of Cl2 is very large, the London Dispersion overcomes the dipole dipole and the L.D. in HCI. Cl2's high molar mass makes it more polarizable, and that's why it has a higher boiling point.</p>
<p>CollegeBoard is never wrong. </p>
<p>{Sends those CB agents into CC to arrest you....}</p>
<p>On a more serious note, it is entirely possible. Contact them. It couldn't hurt!</p>
