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 the sp2 orbitals of the c-c sigma bond would be lost. 10. How many degrees on unsaturation does a compound with the formula C.H.Clehave? a) 2 63 c4 d) 5 1. Which of the following has the highest priority using the Cahn-Ingold-Prelog Rules? CH 3 C-CH3 -c c-CH3 -O-CH3 -C-CH3

Answer 1

7. Option B, E Alkene.

8. Option A , start numbering from alkene carbon towards methyl group and followed by Br atom.

9. Option D

10. Option A, 2, DU= (2n+2-(r+p))/2

n is no of carbons and r is the no of Hydrogen atoms and p is the no of Cl atoms)

DU=2(4)+2-(4+2)/2=10-6/2=2

11. Option A, highest atiAto number gets first priority.

And double bonded Oxygen gets more priority than single bond oxygen priority.
