Pentane (C5H12) hasa molecular weight of 72 and Hexane(C6H14) has a molecular weight of 86.TheΔT of Hexane is 9.225 degrees C and I'm supposed to predictpentane's ΔT. I don't know how I'm supposed to find theΔT and I need to know if pentane has a stronger or weaker intermolecular force than hexane and explain.
