Answer 2

Hepta-3,4-diene exists as a pair of enantiomers.

The condensed structural formula of hepta-3,4-diene is

#"CH"_3"CH"_2"CH=C=CHCH"_2"CH"_3#

At first glance, it appears that the compound has no stereoisomers.

But it is a derivative of allene (propadiene).

The planes of the #"CH"_2# groups in allene are perpendicular to each other, so a suitable substitution will create a chiral molecule (without a chiral carbon!).

You can check for yourself that the two structures below are indeed nonsuperimposable mirror images of each other (enantiomers).

Answer 3

3,4-heptadiene can exhibit geometric (cis-trans) isomerism due to the presence of a double bond.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
