Naming esters

What is the name for the top structural isomer of propyl Ethanoate, do we treat the two methyl groups as branches, possibly:
1,1-dimethyl methyl ethanote??

[ChenBeier]

No, it is 2-propyl ethanoate or isopropyl ethanoate and n- propyl ethanoate.
Instead of ethanoate acetate is common in use.

Well, we can treat the two methyl groups as branches, and the name for the top structural isomer of propyl ethanoate is 1,1-dimethyl methyl ethanote. This is because the two methyl groups are attached to the same carbon atom, and this carbon atom is also attached to the ethanoate group. This makes 1,1-dimethyl methyl ethanote the most symmetrical of the three possible isomers, and it is therefore the most stable.

The other two possible isomers are 2-methyl propyl ethanoate and isopropyl methyl ethanote. In 2-methyl propyl ethanoate, the two methyl groups are attached to different carbon atoms, and this makes the molecule less symmetrical than 1,1-dimethyl methyl ethanote. In isopropyl methyl ethanote, the two methyl groups are attached to a carbon atom that is also attached to another methyl group, and this makes the molecule even less symmetrical than 1,1-dimethyl methyl ethanote.

As a result, 1,1-dimethyl methyl ethanote is the most stable of the three possible isomers, and it is therefore the most likely to be the product of a reaction that produces propyl ethanoate.

The other two possible isomers are 2-methyl propyl ethanoate and isopropyl methyl ethanote. In 2-methyl propyl ethanoate, the two methyl groups are attached to different carbon atoms, and this makes the molecule less symmetrical than 1,1-dimethyl methyl ethanote. In isopropyl methyl ethanote, the two methyl groups are attached to a carbon atom that is also attached to another methyl group, and this makes the molecule even less symmetrical than 1,1-dimethyl methyl ethanoate

This is wrong. 2-methyl-propylethanoate is based on isobutane, means one C more. Its not an isomer from propylethanoate or 1,1 dimethyl methyl ethanoate.

oh, really? Thanks for your answer

The compound you're referring to is propyl ethanoate, which is also known as propyl acetate. In the IUPAC nomenclature system, we consider the longest carbon chain as the main chain. In this case, the parent chain is the propyl group (three carbon atoms).
The ethanoate (acetate) group is treated as a substituent attached to the main chain. Therefore, the correct IUPAC name for propyl ethanoate is:
Propyl Ethanoate
If you had a different isomer with two methyl groups as branches on the ethanoate group, it would be named accordingly. However, the name you provided, "1,1-dimethyl methyl ethanote," seems to have a slight error. If you could clarify the structure, I could help you with the correct IUPAC name.

There is nothing wrong with the name, but unusual.
