Which, if any, of the dichloroethene molecules drawn in Data Table II (3.) (4.) and (5.) are geometric isomers?
A. cis-1,2-dichloroethene and trans-1,2-dichloroethene
B. trans-1,2-dichloroethene and 1,1-dichloroethene
C. cis-1,2-dichloroethene and 1,1-dichloroethene
D. None are geometric isomers

Answer : The correct option is 150 degrees.

Explanation :

Extensive property : Extensive property are the property which depend on the amount of substance present.

For example : Mass, volume, energy, enthalpy, etc.

Intensive property : Intensive property are the property which do not depend on the amount of substance present.

For example : Color, boiling point, melting point, density, pressure, etc.

The boiling point is an intensive property because it does not depend on the amount of liquid. So, the boiling point will remain same.

Therefore, the answer is 150 degrees.
