Why one of the three structures for c2h2cl2 is nonpolar?
1 answer:
Below are the three possible isomers of chemical formula C₂H₂Cl₂. Among these three isomers the <em>trans</em>-1,2-dichloroethene is non-polar while, remaining two are polar.
Reason:
Reason for this is dipole moment. In case of <em>cis</em>-1,2-dichloroethene and 1,1-dichloroethene, the vectors are reinforcing each other perpendicularly to double bond, hence, giving a net dipole moment and making these two isomers polar in nature.
While, in case of <em>trans</em> isomer the two vectors are cancelling each other as the two chlorine atoms are in opposite directions. Hence, the net dipole moment is zero in this case. So, it is non-polar in nature.

Explanation:
The first step is the production of the <u>carboanion</u> in the compound. We will get the <u>negative charge</u> on the methyl group and the <u>positive charge</u> in the Li atom.
Then the carboanion can <u>attack the acetone</u>. The double bond of the oxo group would <u>delocalized</u> upon the oxygen, generating a positive charge in the carbon that can be attacked by the carboanion formaiting a <u>new C-C bond</u>.
