What is the name of this alkene
CH3-CH2-CH-CH=C-CH3
| |
BR CH2CH3
The name of this alkene can be determined by using the rules of chemical nomenclature. To name an alkene, you need to identify the longest continuous carbon chain containing the double bond and assign it a root name. Then, you count the number of carbon atoms in the chain and add an appropriate prefix to indicate the position of the double bond.
Let's break down the given alkene:
CH3-CH2-CH-CH=C-CH3
| |
BR CH2CH3
First, identify the longest continuous carbon chain that contains the double bond. In this case, the longest chain contains six carbon atoms, so the root name will be derived from hexane.
Next, we need to determine the position of the double bond. The double bond appears between the fourth and fifth carbon atoms in the chain. To indicate this, we use the prefix "4-ene."
Finally, we consider the substituents attached to the carbon chain. In this case, there is a bromine (BR) attached to the fourth carbon, and a methyl group (CH3) attached to the sixth carbon.
Putting it all together, the name of this alkene is 4-bromo-5-methylhex-1-ene.
