229 g Selenium monochloride (exists as dimer) undergoes disproportionation reaction to form Selenium tetrachloride (Y) & element "X". Assuming yield to be 100%; which of the following statements is/are CORRECT? (Atomic mass: Se = 79; Cl = 35.5)
Options:(select one or more)
Answer:
B, C, D
Solution:
229 g Se₂Cl₂ = 1 mol. 2Se₂Cl₂ → SeCl₄ + 3Se.
Thus 0.5 mol SeCl₄ forms and its hydrolysis gives 3 mol H⁺.
SeO₂ is solid and acidic. Se₂Cl₂ has C₂ symmetry. Therefore B, C and D.
