The IUPAC name of the compound CH2(COOH)2 is
Open in App
Solution
The correct option is C Propane-1,3-dioic acid
There are two −O||C−OH or carboxylic acid groups . Both of them should get the lowest possible numbers. Hence there is only one way of numbering.
word root = prop
primary suffix = ane
secondary suffix = dioicacid
(since there are two carboxylic acid groups)
Hence the IUPAC name is :
propane -1, 3-dioicacid
Note : The word root 'prop'(-3 carbon atoms) is arrived at using carbon atoms which are part of the functional group.
