Other Nether What is the TUPAC name of the following compound? -CH3 a) 3-Bromo-2-methylcyclohexene 2-Bromo-1-methylcyclohexene b) 1-Bromo-2-methyl-2-cyclohexene d) 6-Bromo-1-methylcyclohexene 9. Carbon-carbon double bonds do not freely rotate like carbon-carbon single bonds. Why? a) The double bond is much stronger and thus more difficult to rotate b) Overlap of the two 2p orbitals of the pi bond would be lost c) The shorter bond length makes it difficult for the attached groups to rotate past each other. d) Overlap of...
