Question

Which statement is correct for the conversion of ROH to RX by reagents $(SOC{l}_2,PB{r}_3,PC{l}_3,P{I}_3)$ and TsCl compared to using HX?

• A. No rearrangement occurs with predictable stereo-chemistry by reagents
• B. Reagents are not useful for $3^{\circ }$ alcohols, while HX reacts easily with $3^{\circ }$ alcohols involving no rearrangement
• C. Reagents must be used in anhydrous conditions because all react vigrously with $H_{2}O$ and they produce harmful gases ($S{O}_2$, HCl, HBr, and HI)
• D. All

Answer 1

Answer: (D)

All

All the statements given in options A, B and C are correct for the conversion. Hence option D is correct.
