ICSE X Chemistry Study of Compounds - Ammonia and Nitric Acid
can we write NO as Nitrogen oxide??
CBSE XII Science Chemistry The p-Block Elements
should we memorize bond length in the sturucture of oxides of nitrogen or is the structure enough?
CBSE XII Science Chemistry The p-Block Elements
though nitrogen exhibits +5 oxdn state it does not form pentahalide why (2m)

GROUP 15 ELEMENT QUES .
1) An unknown salt X react with hot conc. 
to produce a brown coloured gass which intensifies on addition on copper turnings . on adding dilute ferrous sulphate olution to an aqueous solution to an aquaeous solution of X and then carefully adding conc. along the sides of testtube , a brown complex Y i formed at the interface between the solution and . identify X and Y and write the reactions involved .
2) A transuclent waxy solid A on heating it on inert atmosphere is converted into its allotropic form B . Allotrope A on reaction with very dilute aqueous NaOH LIBERATES a highly poisonous gas C having rotten fih mell . The ubstance A reacts with excess of chlorine to form D which hydrolysis to form compound E .Identify A to E . Also write the reaction involved
Thankyou
