$(\mathrm{R_3Ge})_2$ on photolysis gives a radical which shows ESR spectrum. The ESR signals carrying the signature of $^{73}\mathrm{Ge}\ (\mathrm{I}=9/2)$ are in terms of
(a)Nine lines
(b)Ten lines
(c)Two lines
(d)One line
Answer
Answer: B ✓ checked by 4AB · confidence high
Explanation
Coupling to ⁷³Ge (I = 9/2) gives 2I + 1 = 10 lines.
