Which compound is an isomer of C2H5OC2H5?
Answer and Explanation:
Isomers are compounds that have exactly the same number of atoms of same elements but different structure. Therefore, we first need to count numbers of atoms in the compound C2H5OC2H5. There are 4 Carbon atoms, 10 Hydrogen atoms and 1 oxygen atom. Let's compare this to the number of atoms in the answer choices. Choice 1: (CH3COOH): 2 Carbon atoms, 4 Hydrogen atoms and 2 oxygen atoms, Choice 2(C2H5COOCH3): 4 Carbon atoms, 8 Hydrogen atoms and 2 oxygen atoms. Choice 3 (C3H7COCH3): 5 Carbon atoms, 10 Hydrogen atoms and 1 oxygen atom. Choice 4(C4H9OH ): 4 Carbon atoms, 10 Hydrogen atoms and 1 oxygen atom. Therefore the last answer choice, 4, is the correct answer.
