In a sample of ethyl ethanote `(CH_(3)COOC_(2)H_(5))` the two oxygen atoms have the same number of electrons but different number of neutrons, which of the following is the correct reason for it?

Options

A. one of the oxygen atoms have gained electrons
B. One of the oxygen atoms has gained two neutrons
C. The two oxygen atoms are isotopes
D. The two oxygen atoms are isobars

Explanation

To solve the question regarding the two oxygen atoms in ethyl ethanoate `(CH3COOC2H5)` having the same number of electrons but different numbers of neutrons, we can follow these steps:

### Step 1: Understand the Composition of Ethyl Ethanoate
Ethyl ethanoate is a chemical compound with the formula `(CH3COOC2H5)`. It contains carbon (C), hydrogen (H), and oxygen (O) atoms.

### Step 2: Identify the Number of Electrons in Oxygen
Each oxygen atom has an atomic number of 8, which means each oxygen atom has 8 protons and, in a neutral atom, also has 8 electrons. Therefore, both oxygen atoms in the compound have the same number of electrons.

### Step 3: Understand the Concept of Isotopes
Isotopes are atoms of the same element that have the same number of protons (and hence electrons in neutral atoms) but different numbers of neutrons. This results in different mass numbers for the isotopes.

### Step 4: Apply the Concept to the Oxygen Atoms
Since the question states that the two oxygen atoms have the same number of electrons (8) but different numbers of neutrons, this indicates that they are isotopes of oxygen. For example, one could be oxygen-16 (with 8 neutrons) and the other could be oxygen-18 (with 10 neutrons).

### Step 5: Conclusion
Therefore, the correct reason for the two oxygen atoms in ethyl ethanoate having the same number of electrons but different numbers of neutrons is that they are isotopes of oxygen.

### Final Answer
The two oxygen atoms are isotopes because they have the same number of electrons (8) but different numbers of neutrons.
