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?

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

Text Solution

Verified by Experts

The correct Answer is:
C
The two O-atoms in `CH_(3)COOC_(2)H_(5)` can have different number of neutrons only if the two O-atoms are isoropes. It is because, isotopes of an element have same number of protons (and electrons) but different number of neutrons.
