• A. $C{H}_{3}C{H}_{2}COO{C}_2{H}_5\leftarrow$ ethyl butanoate
• B. $C{H}_{3}CH\left(C{H}_3\right)C{H}_{2}CHO\leftarrow$ ethyl butanoate
  
• C. $C{H}_{3}CH\left(C{H}_3\right)COC{H}_{2}C{H}_3\leftarrow$ 2-methyl-3-pantanone
  
• D. $C{H}_{3}CH\left(C{H}_3\right)CH\left(OH\right)C{H}_3\leftarrow$ 2-methyl-3-butanol

Answer 1

Answer: (A), (D)

The correct options are
A $C{H}_{3}C{H}_{2}COO{C}_2{H}_5\leftarrow$ ethyl butanoate
D $C{H}_{3}CH\left(C{H}_3\right)CH\left(OH\right)C{H}_3\leftarrow$ 2-methyl-3-butanol

The correct name of ; $C{H}_{3}C{H}_{2}COO{C}_2{H}_5$ is Ethyl propionate.
The correct name of ; $C{H}_{3}CH\left(C{H}_3\right)-CH\left(OH\right)-C{H}_3$ is 3-methyl 2-butanol.
