Which of the following is not hydrolysed
Due to absence of d - orbital in N - atom, it can't accept e– from $ H_2O for hydrolysis of NF_3 $
Which of the following is the most basic oxide
Which of the following has highest B.P
$ NH_3 PH_3 AsH_3 SbH_3 $ BP \rightarrow 238.5 185.5 210.6 254.6
Which of the following exihibits highest solubility in $ H_2O $
Ammonia ($NH_3$) exhibits the highest solubility in water. This is due to the hydrogen bonding between the $NH_3$ molecules and $H_2O$ molecules. Ammonia has a lone pair of electrons on the nitrogen atom, which can form hydrogen bonds with water molecules, making it highly soluble.
$ HNO_3 $ in aqueous solution yields
The three important oxidation state of P are
Phosphorus (P) mainly exhibits three oxidation states: -3, +3, and +5. In the -3 oxidation state, phosphorus forms compounds like phosphine ($PH_3$). In the +3 oxidation state, it forms compounds such as phosphorus trichloride ($PCl_3$). In the +5 oxidation state, it forms compounds like phosphorus pentachloride ($PCl_5$) and phosphoric acid ($H_3PO_4$).
Which show maximum valency
P Shows + 5 valency.
Which oxide of N is obtained on heating ammonium nitrate at $ 250 ^\circ $ C
When ammonium nitrate ( ext{NH}_4 ext{NO}_3) is heated to about 250°C, it decomposes to form nitrous oxide ( ext{N}_2 ext{O}) and water. The reaction is as follows: $$ ext{NH}_4 ext{NO}_3 ightarrow ext{N}_2 ext{O} + 2 ext{H}_2 ext{O} $$
The number of P-O-P bonds in cyclic metaphos phoric acid is
Cyclic metaphosphoric acid ( ext{HPO}_3)_n contains three ext{P-O-P} bonds in its ring structure. The structure can be represented as a cyclic trimer with the formula ( ext{HPO}_3)_3. Each phosphorus atom is bonded to two oxygen atoms, which in turn are bonded to two different phosphorus atoms, creating three ext{P-O-P} linkages.
The product oblained by heating $ (NH_4 ) SO_4 and KCNO $ is
$ (NH_4)2SO_4 + KCNO \rightarrow NH_4CNO + K_2SO_4 \rightarrow NH_2CONH_2 urea $
