1.	On heatingwith concentratedNaOH solution in an inert atmosphere of CO_(2) white phorusgivesa gas . Which of the following statementsis incorrect about the gas ?
Answer» It ismore basicthan `NH_(3)` Its solution in water decomposes in the presence of light It is LESS basic than `NH_(3)` It is highly poisonnous and has smell like rotten fish . Solution :`P_(4) +3NOH+3H_(2)O overset (Delta) underset (CO_(2)) to 3NaH_(2)PO_(2)underset ("Phosphine")( +PH_(3) uarr)` `PH_(3)`is less basic than `NH_(3)` as the electron DENSITY is diffused over the LARGER phosphorus atom .
