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-dimethyM-oxo pent-2-en-l-oic-acid
Correct Answer: D
Solution :
The order of preference is\[COOH>>C=0\] Thus, \[\underset{2,\text{ }3-dimethyl-4-oxopent-2-en-1-oic\text{ }acid}{\mathop{\overset{5}{\mathop{C{{H}_{3}}}}\,-\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{^{4}C}}\,-\underset{\begin{smallmatrix} | \\ C{{H}_{3}} \end{smallmatrix}}{\mathop{\overset{3}{\mathop{C}}\,}}\,=\underset{\begin{smallmatrix} | \\ C{{H}_{3}} \end{smallmatrix}}{\mathop{\overset{2}{\mathop{C}}\,}}\,-\overset{\begin{smallmatrix} O \\ ||1 \end{smallmatrix}}{\mathop{^{4}C}}\,-OH}}\,\]
