Question

give the iupac name of CH3 CH2CH(CH3)COOC2H5​

Answer 1

Answer:

ethyl -2-methylbutanoate

Answer 2

Answer:

Ethylbut-2-enoate

Explanation:

IUPAC nomenclature of this compound is very easy . First we have to identify the functional group in this compound that is ester . Now , we know that ester is named as alkyl alkanoate and ester is always placed between any hydrocarbon chain so there will be two parts of chain from the functional group

CH3-CH=CH || COO || C2H5

Now we will see which part is attached to carbon and which part is attached to oxygen . The part which is attached to oxygen will named as alkyl so it will be ethyl and the part which is attached to carbon will be named as alkanoate and remember the carbon atom which is present in the functional group will also be added in this part but we can see that there is also a double bond present in this part so for naming first we will see the number at which double bond is placed

CH3=CH=CH-COO

4 3 2 1

so it will be but-2-enoate .
