Draw an acceptable structure for (z)-2-chloro-4-ethylhex-2-ene.

Answer :

There are two types of configurations :

(1) E-configuration         (2) Z-configuration

On assigning of the configurations, the group's priorities depends upon the atomic number of the atom attached to the double bond. The higher the atomic number, the higher the priority of the group.

E-configuration : When two groups of higher priority are on opposite sides of the double bond.

Z-configuration : When the two groups of higher priority are on the same side of the double bond.

The acceptable structure for (Z)-2-chloro-4-ethylhex-2-ene is shown below.

indium, and thallium have three electrons i think

i think it's c. i'm not sure but i think so.
