A) 4-oxo-2, 3-dimethyl pent-2-en-l-oic acid
B) 2-carboxy-3 methyl pent-2-en-3-one
C) 4-carboxy-3 methyl pent-3-en-2-one
D) 2, 3-dimethyl-4-oxo pent-2-en-l-oic acid
Correct Answer: D
Solution :
The order of preference is \[-COOH>>C=O\] Thus, \[\overset{5}{\mathop{C}}\,{{H}_{3}}-\overset{O}{\mathop{\overset{4||}{\mathop{C}}\,}}\,-\underset{C{{H}_{3}}}{\mathop{\underset{|}{\overset{3}{\mathop{C}}}\,}}\,=\underset{C{{H}_{3}}}{\mathop{\underset{|}{\overset{2}{\mathop{C}}}\,}}\,-\overset{O}{\mathop{\overset{||1}{\mathop{C}}\,}}\,-OH\] 2, 3-dimethyl-4-oxopent-2-en-1-oic acidYou need to login to perform this action.
