Solution

Solution Steps

Step 1: Find the longest carbon chain

The longest chain contains 5 carbons.

Step 2: Identify the substituents

There is a bromine atom on carbon 3, and two ethyl groups, one on carbon 2 and another on carbon 3.

Step 3: Number the carbon atoms in the main chain

Start numbering from the end closest to the first substituent, resulting in the bromine being on carbon 3.

Step 4: Name the substituents with their respective positions

The substituents are 3-bromo, 2-ethyl, and 3-ethyl. Arranging these alphabetically gives 3-bromo, 2-ethyl, 3-ethyl.

Step 5: Combine the name of the main chain and the substituents

The main chain is pentane, as there are no double or triple bonds. Adding the substituents, we have 3-bromo-2-ethyl-3-ethylpentane.

Step 6: Account for the aldehyde group

The aldehyde functional group takes priority, therefore the main chain is actually a butanal chain, with the aldehyde group on carbon 1. This means the substituents become 2-bromo, 3-propyl, and 3-ethyl.

Final Answer: 2-bromo-3-ethyl-3-propylbutanal
