Question

Write I.U.P.A.C. names of the following compounds: \( CH_3CH(CH_3)CH_2CH_2CH_2CHO \)

Hint:

In aldehydes, numbering starts from the carbonyl carbon, and substituents are named accordingly.

Answer 1

Step 1: Identify the longest carbon chain containing the aldehyde group. The parent chain contains 6 carbons, making it a hexanal. Step 2: Number the chain starting from the aldehyde functional group. A methyl group is attached to carbon 3. Step 3: The IUPAC name is: \[ 3\text{-methylhexanal} \]
