The ozone layer protects humans from harmful UV rays, because it acts as a sort of filter for any toxic or overpowering waves from damaging our skin. This goes for animals, as well.
The 1930s saw natural disasters as well as manmade ones: For most of the decade, people in the Plains states suffered through the worst drought in American history, as well as hundreds of severe dust storms, or "black blizzards," that carried away the soil and made it all but impossible to plant crops.
The structures shown are examples of Constitutional Isomer.
In Chemistry, an isomer refers to a molecule that is similar to another but has differences. These differences can be:
- A difference in the constitution: The molecules have the same formula but the connectivities between elements or arrangement is different.
- Arrangement in space: The molecules have the same formula and connectivity, but they look different to do an arrangement in space of a position.
The molecules shown have the same formula because the elements in each pair are the same. However, the way these elements are connected is slightly different because the Br and the CH3 are connected to different carbons.
Based on this, the difference is the connectivity or constitution, and therefore these are constitutional isomers.
