In problems 4.28 to 4.51, refer to Table 4.3 for isotopic abundances where needed.

The ²⁹Si NMR spectrum of compound 4.15 shows a triplet with a coupling constant of 194 Hz. 

(a) Rationalize these data  

(b) Predict the nature of the signal in the ¹H NMR spectrum of 4.15 that is assigned to the silicon-bound protons. [²⁹Si: 4.69% abundant; I = 1/2]
