Question

7. Draw a stereoisomer of a methyl-substituted cyclopentanediol that is optically active. Determine the configuration of the chiral centers. 8. Draw five molecules that each contain a C-atom as a carbocation; ensure the carbocations are of different stabilities. 9. Draw a ketone that in a mass spectrometry analysis will give, among others, a fragment at m/z = 29 and has a molecular mass of 128 g/mol.
