Welcome to WebSpectra – This site was established to provide chemistry students with a library of spectroscopy problems. Interpretation of spectra is a technique that requires practice – this site provides 1 H NMR and 13 C NMR, DEPT, COSY and IR spectra of various compounds for students to interpret. Hopefully, these problems will provide a useful resource to better understand spectroscopy.

A carbocation is an organic molecule, an intermediate, that has a carbon atom bearing a positive charge and three bonds instead of four. Since the charged carbon atom does not satisfy the octet rule, it is unstable and therefore highly reactive. Carbonate ions are classified into primary #(1^o)#, secondary #(2^o)#and tertiary#(3^o)#.

Vapor Pressure Lowering of Solutions. In a solution, a fraction of the molecules with energy in excess of the intermolecular force are nonvolatile solute molecules, or another way of saying this is that the number of solvent molecules with energies above the intermolecular force has been reduced.

Difference between intermediates and transition states. Whereas, transition state is just the state before formation of new molecule (involves breaking of bonds of reactants and formation of new ones) An intermediate differs from a transition state in that the intermediate has a discrete lifetime (be it a few nanoseconds or many days), whereas a transition state lasts for just one bond vibration cycle.
