Answer:
3,5-dimethyl-2-octene
Explanation:
The parent chain will be choosen based on the highest value. In this case, if we count from top to bottom, we'll get seven carbon, however if we count from the second carbon, going left and then down, we'll get eight carbon. So the parent chain is octene
The double bond is located at the second carbon and the methyl groups are located on carbon 3 & 5. Since there are two methyl groups, we add di- in front of methyl to indicate two methyl groups present.
Note: The functional group has to be prioritise and it needed to be a part of the parent chain. In this case, the functional group is the double bond. (alkene)
Birds use the magnetic fields and some fish i believe as well and maybe butterflies im not entirely sure <span />
Acetic Acid has two C atoms, four H atoms, and two O atoms, so the molecular formula is C2H4O2.
