Not necessarily.
<h3>Explanation</h3>
Isomers might differ in polarities. They will end up with different physical properties such as melting points.
Example:
- 1,2-dichlorobenzene has a melting point of around -18 ~ -17 degrees celsius. (SynQuest)
- 1,4-dichlorobenzene (with two chlorine opposite to each other on a benzene ring) has a melting point of 52 ~ 54 degrees celsius. (SynQuest)
Both 1,4- and 1,2-dichlorobenzene contains two chlorine atoms connected to a benzene ring. The two molecules are structural isomers.
The two chlorine atoms are adjacent to each other in the 1,2 isomer. The molecule is asymmetric and polar.
The two chlorine align with an axis of symmetry in the 1,4 isomer. The molecule is symmetric. The dipoles would cancel out to produce a nonpolar molecule.
Dipole-dipole interactions are typically stronger than <em>induced</em> dipole<em> </em>in isomers. As a result, the 1,2 isomer has a higher melting point.
Since you have not included the figures with the diagrams to select the right answer, I am going to explain the main differences that lead you to differentiate electrochemical cells.
There are four important terms needed to identify the electrochemical cells: electrolysis, electrochemical cells, electrolitc cells and voltaic cells.
1) Electrochemical cell: is a device that uses a chemical reaction (redox reaction) to produce electricity or that uses electricity to product a chemical reaction.
2) Electrolysis: is the production of a chemical reaction using electricity.
3) Electroltic cell: is one of the two types of electrochemical cell. It is that in which electricity is used to produce the chemical reaction, i.e. where electrolysis happens. For example, the decomposition of sodium chloride brines is done in an electrolitic cell.
4) Galvanic cell: is the other type of electrochemical cell. It is that in which chemical reactions (redox reactions) produce electricity. The battery of the car is an example of a galvanic cell.
Here you are asked to identify which diagram shows a voltaic cell.So, you need to lool at:
- a redox reaction is happening
- this redox reaction is producing electricity (not that the electricity is producing the reaction)
Remember that a redox reaction is where some atoms are being reduced (gaining electros) and others are being oxidized (losing electrons).
Tha information will let you to choose the righ diagram.
