|
2
|
|
How many elements of unsaturation implied by molecular formula C8H11N?
|
3.5 --> 4
|
|
what two atomic orbitals or hybrid atomic orbitals overlap to form the C--C (double) sigma bond in ethylene?
|
C sp2 + C sp2
|
|
why is rotation about the carbon-carbon double bond in alkenes prohibited while relatively free rotation can occur about the carbon-carbon single bond in alkanes?
|
because in a double bond rotation would require breaking one of the bonds, costing a great deal of energy
|

provide the reagents necessary for carrying out the transformation of cyclopentANE to cyclopentENE
|
Br2, hV; NaOH, acetone
|
|
which of the following statements best describes the relative bond dissociation energies of the sigma and pi bonds present in the carbon-carbon double bond of an alkene?
|

|
|
which of the following best approximates the CCC bond angle of propene
|
120 degrees
|
|
which of the following alcohols is (are) likely to yield a product where skeletal arrangement has occurred when treated with sulfuric acid
|
both 3,3-dimethyl-2-butanol and 2,2-dimethylcyclohexanol

|
3,2-dichloro-2-pentene
