3.6
Compounds a and c have only one possible structure because in each case one of
the carbons of the double bond has two identical substituents:
a.
b.
c.
d.
3.7
The electron pair in a
σ
bond lies directly between the nuclei it joins. In a
π
bond, the
electron pair is further from the two nuclei that it joins. Therefore more energy is
required to break a
σ
bond than a
π
bond.
3.8
a.
One bromine atom adds to each doubly bonded carbon, and the double bond
in the starting material becomes a single bond in the product:
