Answer:
D) C₄H₉OH
Step-by-step explanation:
In chemistry, isomers are chemical substances with the same formula (That is, same atoms but in different structures).
For the compound C₂H₅OC₂H₅ there are 4 atoms of C, 10 atoms of H and 1 atom of O.
A) CH₃COOH . This compound have 2 atoms of C, 4 atoms of H and 2 atoms of O. Thus, isn't an isomer.
B) C₂H₅COOCH₃. There are 4 atoms of C but 8 atoms of H and 2 atoms of O. Isn't an isomer
C) C₃H₇COCH₃. There are 5 atoms of C, 10 atoms of H and 1 atom of O. Thus, isn't an isomer
D) C₄H₉OH. Here, you have 4 atoms of C, 10 atoms of H and 1 atom of O. That means this structure is the isomer of C₂H₅OC₂H₅
