Question
Which of the following disproportionate(s) on heating with sodium hydroxide ?
Options
A.P4
B.S8
C.Cl2
D.B.
Solution
(A) P4 + 3 NaOH + 3 H2O → PH3 + 3 NaH2PO2
(B) 4S + 6 NaOH
Na2S2O3 + 2 Na2S + 3 H2O
(C) 3 Cl2 + 6 NaOH → 5 NaCl + NaClO3 + 3 H2O
(D) 2B + 6 NaOH → 2 Na3BO3 + 3 H2
(B) 4S + 6 NaOH
Na2S2O3 + 2 Na2S + 3 H2O(C) 3 Cl2 + 6 NaOH → 5 NaCl + NaClO3 + 3 H2O
(D) 2B + 6 NaOH → 2 Na3BO3 + 3 H2
