JEE Main 2022 (25 Jul Shift 1)

Question

SO2Cl2 on reaction with excess of water results into acidic mixture SO2Cl2+2H2O→H2SO4+2HCl 16 moles of NaOH is required for the complete neutralisation of the resultant acidic mixture. The number of moles of SO2Cl2 used is

Correct answer
C4

Step-by-step explanation

SO2Cl2+2H2O→2HCl+H2SO4

Let x moles of SO2Cl2 are required,

∴ nH2SO4=x,nHCl=2x

⇒nH+=4x

Moles of H+ formed =4x

Moles of OH- from 16 moles of NaOH=16

4x=16 (for complete neutralisation)

x=4
