Question

Among the following, the group of molecules that undergoes rapid hydrolysis is (A) SF6,Al2Cl6,SiMe4 (B) BCl3,SF6,SiCl4 (C) BCl3,SiCl4,PCl5 (D) SF6,Al2Cl6,SiCl4

Tardigrade Admin · Accepted Answer

BCl3,SiCl4 and PCl5 get radily hydrolysed to give orthoboric, orthosilicic and phosphoric acid respectively. BCl3+3H2O arrow H3BO3+3HCl SiCl4+4H2O arrow H4SiO4+4HCl PCl5+H2O arrow POCl3+2HCl oversetH2 O (e x c e s s) arrow H3PO4+HCl
