Question:

(a) The 31P and 11B NMR spectra of Pr3P·BBr3 (Pr = n-propyl) exhibit a 1 :1 :1 :1 quartet (J = 150 Hz) and a doublet (J = 150 Hz), respectively. Explain the origin of these signals.

(b) Discuss the factors that contribute towards [NH4][PF6] being soluble in water.

(c) The ionic compound [AsBr4][AsF6] decomposes to Br2, AsF3 and AsBr3. The proposed pathway is as follows:
