Consider the hydrocarbon below. a skeletal model has line segments that slant down, run flat in a double bond, slant up, and run
1 answer:
The correct answer would be the structure attached of the form slant up, then run flat in a double bond, slant up and run flat.
<h3><u>Cis-Trans isomerism(GEOMETRIC ISOMERS)</u></h3>- Cis-trans isomers are compounds that, as a result of the existence of a hard-structure in their molecule, have distinct configurations (elements that are constantly in distinct places in space).
- Cis-trans isomerism may be seen in alkenes and cyclic molecules.
- trans-isomers: the two hydrogen atoms are on opposite sides.
- cis-isomers: the two hydrogen atoms are on the same side, as are the two carbon groups.

Answer: Option (c) is the correct answer.
Explanation:
As we know that density the amount of mass present in per unit volume.
Mathematically, Density =
So, it means that density is inversely proportional to volume. Hence, when there will be decrease in density of a substance then there will be increase in its volume. That is, expansion of substance will take place.
Also, boiling point of copper is 2,562 degree celsius but we are heating it up to a temperature of 95 degree celsius. This means that copper will remain in liquid state at this temperature.
Thus, we can conclude that a change which occurs in a sample of copper is that copper sample will expand.
