JEE Main 2021 Chemistry question

was leached with alkali to get X. The solution of X on passing of gas Y, forms Z. X,Y and Z respectively are :

• (A)X = Na[Al(OH)4], Y = SO2, Z = Al2O3
• (B)X = Na[Al(OH)4], Y = CO2, Z = Al2O3, xH2OCorrect
• (C)X = Al(OH)3, Y = CO2, Z = Al2O3
• (D)X = Al(OH)3, Y = SO2, Z =Al2O3.xH2O
