28/7/2018· For example polystyrene will be solvated better by benzene than by hexane for this reason. This good ability to dissolve things is why I regard benzene as a good solvent. It is a good solvent to dissolve things but often a bad thing to work with in the lab.
Why is benzene flat in shape? - Quora
Because this will make benzene molecule more stable. Being flat allows 6 unused p-orbitals of all six carbon atoms to overlap with each other in a symmetric hexagon and allows 6 unused electrons to move freely along the overlapped orbitals. In this overlapping, six new molecular orbitals are formed from six original atomic orbitals.
