esters nomenclature
 
 
Solution
 
 
esters nomenclature
1. Functional group: carboxylic acid
2. Numbering: g. functional with minor locator
3. Substituents: ester ( methoxycarbonyl ) in 4
4. Name: 4 - Methoxycarbonyl butane oic acid
 
 
 
 
 
1. Functional group : carboxylic acid
2. Numbering: g. functional with minor locant (unnumbered its carbon)
3. Substituents: 3 bromo and 5- ( methoxycarbonyl ) ester
4. Name: 3 - Bromo - 5 - Methoxycarbonyl- Cyclohexane Carboxylic Acid
 
 
 
 
 
1. Functional group: carboxylic acid
2. Numbering: g. functional with minor locator
3. Substituents: ester ( ethoxycarbonyl ) in 5
4. Name : 5 - ethoxycarbonyl hexane oxide



{nota}When a molecule contains carboxylic acids and esters, the acid takes precedence and the ester is renamed alkoxycarbonyl{/nota}
