In order of increasing Bp?
A: CO2 ,N2 ,CS2, KCl, H2O, glycerine and why?
B: ethane, chloroethane, n-, isobutane, ethanol AND WHY?

with branching, the surface
area decreases..And with decrease in surface area ,van der Waals
interactions also decreases,so boiling point also decreases..Hence
n- butane has higher b.p than iso butane (which is more
branching)
