A) 1-formyl-3-oxopentanoic acid
B) 5-formyl-3-oxopentanoic acid
C) 3-oxo-5-formylpentanoic acid
D) 3-oxo-1-formylpentanoic acid
Correct Answer: B
Solution :
\[OHC-\underset{5}{\mathop{C}}\,{{H}_{2}}-\underset{4}{\mathop{C}}\,{{H}_{2}}-\overset{O}{\mathop{\overset{||}{\mathop{\underset{3}{\mathop{C}}\,}}\,}}\,-\underset{2}{\mathop{C}}\,{{H}_{2}}-\underset{1}{\mathop{C}}\,OOH\]Carboxylic group is given priority over \[-CHO\] and group. Hence, its IUPAC name is 5-formyl-3-oxo-pentanoic acid.You need to login to perform this action.
