(a) 3

(b) 2

(c) 4

(d) 5

This question was addressed to me during an interview.

My question is based upon Quantum Efficiency in portion Photochemistry of Engineering Chemistry I

Answer 1

Right option is (a) 3

Best explanation: Photochemical reactions can be divided into three categories on the basis of quantum efficiency i.e., the reactions in which quantum yield is “a small integer like 1, 2” OR “less than 1” OR “a very high value”.
