Answer:
The IUPAC name of the given structure is 2,4- dimethyl 3- pentanone.
Our first step is to pick the longest chain. Here, every combination gives 5 carbons.
As no double bond or triple bond exists between the carbons, we name it as an alkane.
There are methyl substituents on 2 and 4 positions ( named in any way) therefore we start the naming with 2,4- dimethyl.
Our functional group is carbonyl ( C = O ). It is not a chain- terminating functional group like carboxylic acid or aldehyde or carbonitrile( -CN ).
Therefore, we name it as 3- alkanone.
Keep in mind that if the functional group was an aldehyde instead, we would have to start naming from the carbon attached to the functional group instead of from any other carbon.
