Question

For each of the pairs of alkenes below, indicate whether measurements of polarity alone would be sufficient to distinguish the compounds from one another. If so, which is more polar

Answer 1

Answer:

The alkenes are shown below in the drawing, indicating  which is more polar.

Explanation:

In the first pairs of alkenes, the 1-butene have a dipole moment due to the inductive effect of the group, instead the trans-2-butene do not present it since the dipoles are counteracted.

In the second pair of alkenes the cis hex-2-ene is more polar because the substituents provide greater dipole moment to the molecule.

For the last pair of alkenes, the same  happens as in the first pair of alkenes, in the hex-3-ene trans compound the dipole moments are canceled.
