Which has the highest boiling or melting point? provide a brief reasona) boiling point: H3CCH2CH2CH2CH2CH2CH3 or H3CCH2CH2CH2CH2CH3b) boiling point: H3CCH2CH2CH2CH2CH2OH or H3CCH2CH2CH2CH2OCH3c) boiling point: H3CCH2CH2CH2CH2CH2CH3 or H3CCH2CH2CH2CH2CH2Cl
On the basis of strength of intermolecular forces, which of the following elements would be expected to have the highest melting point? (A)# Br_2 # (B) #Cl_2# (C) #F_2# (D) #Kr# (E) #N_2# I understand that LDF strength increases with increasing charge and increasing molecular size. Based on that, would not #Kr# has the strongest LDF and hence the highest melting point? Why is #N_2# the correct answer?
intermolecular forces Rank the following substance from highest melting point to lowest melting point. My teacher gave a list of compounds: H2O, NO2,F2,CI2 and to have a high melting point means that you need a stronger IMF. Rank the following substances from highest freezing point to lowest. Same compounds from above. What would I do in this instance? Would I list this from lowest IMF to high IMF.
