(a) Why does PCI_3fumes in moisture ?(b) NO_2dimerises to N_2O_4 ? |
|
Answer» Solution :(a)` PCl_3` produces HCl GAS in MOISTURE. Hence `PCI_3`fumes in moist air, `PCl_3 + 3H_2O to H_3PO_3 + HCl` (B) `NO_2`has one unpaired electron on N, ` therefore NO_2`dimerises to PAIR up unpaired electron `O_2N + NO_2 to O_2N - NO_2 " or" N_2O_4` |
