MeNHCH2CH2NH2 forms a square planer complex with a M of formula, M(MeNHCH2CH2NH2)2 in which each N atom binds to the metal to give the esquire planer complex. sketch each diastereomer of this complex. in drawing the structure pay very close attention to: a) the relative location of the two N atoms bound to the Me groups to one another. b) relative orientations (up and down) of the two Me groups to one another. Designate each isomer as cis or trans and also indicate if it is chiral or not. indicate the one isomer that dose not have a plane of symmetry but is not chiral.
When 35.0 g of an unknown nonelectrolyte is dissolved in 220.0 g of benzene, the solution boils at 83.2°C. Calculate the molecular weight of the unknown nonelectrolyte. The Kb for benzene = 2.53°C/m. The boiling point of pure benzene is 80.1°C.
