Rank these five scenarios from lowest freezing point (1) to highest freezing point (5). each solution was made using 1.0 kg water as the solvent and the indicated number of moles of each solute. 0.5 mol nacl 1.0 mol k3po4 2.0 mol glucose 1.5 mol ethylene glycol 0.8 mol mgcl2

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
