Question

Choose total number of correct reactions.
(i) When CuSO4 solution reacts with NH3, complex is formed.
(ii) When CuSO4 solution react with PH3, complex is formed.
(iii) C12H22O11 $\xrightarrow{ ext{conc.H}_2 ext{SO}_4}$ 2C + 11H2O
(iv) NH3 + Cl2 (excess) $\xrightarrow{\Delta}$ NH4Cl + N2
(v) NH3 (excess) + Cl2 $\xrightarrow{\Delta}$ NCl3 + HCl
(vi) HNO3 + P4O10 $\xrightarrow{\Delta}$ HPO3 + N2O5
(vii) S + H2SO4 $\xrightarrow{\Delta}$ SO2 + H2O
(viii) SbF5 + XeF4 $ ightarrow$ [SbF4][XeF5]
(ix) XeF4 + O2F2 $ ightarrow$ XeF6 + O2

Correct answer: 7 / 7 CORRECT REACTIONS (REACTIONS II AND VIII ARE INCORRECT; E.G. CUSO4 + PH3 FORMS CU3P2 BLACK PPT, SBF5 + XEF4 FORMS [XEF3]+[SBF6]-). Step 1: Sublimation occurs in molecular solids that have relatively weak intermolecular forces in the solid state. Step 2: Anhydrous aluminum chloride has a dimeric structure, Al2Cl6, where individual dimers are held together only by weak van der Waals forces. Step 3: Because of these weak intermolecular forces, heating anhydrous AlCl3 causes it to sublime directly from the solid to the gas phase at around 180°C, matching option (d).
