Your are correct, but do you know why?
 
  • #5
i believe B and C are dipole-dipole forces, which are stronger than A and D which are london disperion forces. i know dipole-diople is stronger than london. Would the answer be C since it has the longest carbon chain that is polar.

thanks

Keep working at it... "C" (1-butene) is NOT CORRECT!

In which case, I stand corrected. I guess I should stick to Math & Physics, and butt out of chem....:redface:
