In a sample of ethyl ethanoate (CH3COOC2H5), 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?

Atoms of the same element having same atomic number but different mass numbers are known as isotopes.


As the charge is zero implies that there is no change in the number of electrons and also the number of protons in the two oxygen atom is the same as they have the same atomic number. Different number of neutrons implies that they are isotopes.


Hence, the correct option is C.
