Question

Write the IUPAC and common name, if any, for each of the following carboxylic acids:

b. Structural formula of a carboxylic acid with a bromine atom, showing functional groups: -COOH and -Br.

Accepted Answer

Welcome back, everyone predict the systematic and common names of the given molecule. First of all, let's classify the given molecule. And we can see that this is a carboxylic acid because it has a general form of R coo H, right? And we know that carboxylic acids, well, they are essentially named as alcaic acid. Our goal is to first of all identify what alkan OIC is in this case. And we can count the number of carbon atoms in the longest continuous carbon chain. We always want to label carbon number one within carbel itself by definition because this is where our functional group is. So how many carbon atoms do we have in the longest continuous chain? That's five. And we know that the prefix that represents five is pantha. So the acid itself is Pantano acid. From here, we can start considering the substitutions and we can see that there's the chloral substitution bonded to carbon number two, meaning our name will have two chloral and then carbon number four, it has two methyl substituents. We're going to state four, comma four. And we want to use a prefix dye which represents two followed by methyl So four, comma four by muscle means that position four and position four. Again, that specific carbon contains two methyl groups, we simply have to repeat the number because it can be four comma five dimethyl, which would simply mean that there's one metal group bonded to carbon. Number four, another one is bonded to carbon. Number five, right? In total, we still have two metal groups, but the positions differ. So now we want to arrange those substituents alphabetically, right? So if we were to compare C versus M, ignoring the prefix, of course, C gets the alphabetical priority and the complete name would be two Kal or for the muffle followed by the parent name, right? Because now we are done with the substitutions. So Pantano followed by acid. This is a new word, right? That's it. We have determined the systematic name. What about the common name? There will be no common name, common, we can say none. And the reason why there's no common name is simply because this acid is too complex, just looking at it, we have a Chloro substituent, right? And generally we have common names for the assets with simple linear carbon chain, right, such as 234 or five member chain or a branched chain with only carbon atoms. But when we start introducing hetero atoms, the complexity of the chain becomes too significant to actually have a common name. So we only have a systematic name. Thank you for watching.
