Question

Isotope of oxygen used in studying photolysis is

• A. ${}^{16}O$
• B. ${}^{15}O$
• C. ${}^{17}O$
• D. ${}^{18}O$

Answer 1

The correct option is D ${}^{18}O$

A) ${}_{}^{16}O$ is not used to study photolysis.
B) ${}_{}^{15}O$ is not used to study photolysis.

C) ${}_{}^{17}O$ is not used to study photolysis.

D) ${}_{}^{18}O$ is the isotope that is abundantly present and is used in the study of photolysis.
So the correct answer is '${}_{}^{18}O$'.
