Which compound is an isomer of C2H5OC2H5? A)CH3COOH

B)C2H5COOCH3

C)C3H7COCH3

D)C4H9OH

D) C₄H₉OH

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
