Question

1. In a sample of ethyl ethanoate (CH² COOC²H) 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?
(a) One of the oxygen atoms has 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.​
