Which of the patterns (A,B,C or D) fits best with the ${ }^{\mathrm{13}} \mathrm{C} ~ N M R$ spectrum of $\mathrm{TiCl}_{\mathrm{3}}\left(\mathrm{CDH}_{\mathrm{2}}\right)$, [Given: $\mathrm{J}_{(\mathrm{C}-\mathrm{H})}^{\mathrm{1}} > \mathrm{J}_{(\mathrm{C}-\mathrm{D})}^{\mathrm{1}}$ ] 
(a)(b)
(b)(d) ANSWER KEY
Answer
Answer: B ✓ checked by 4AB · confidence medium
Explanation
¹³C is split by two H (large ¹J) into a 1:2:1 triplet, and each line again by one D (I = 1) into a 1:1:1 triplet. That gives three groups of three lines, the central group twice as intense (b).
