Question

Which of the following dissolves in water but does not give any oxyacid solution

• A. $SO_2$
• B. $OF_2$
• C. $SCl_4$
• D. $SO_3$

Answer 1

Answer: (B)

$OF_2$

Answer 2

$OF_2$ dissolves in water but does not give any oxyacid solution. While $SO_2, SCl_4$ and $SO_3$ give oxyacid solution in water. {SO_2 + H_2O ->\underset{\mathrm{ Sulphurous acid }}{ { H_2SO_3 }}} {SCl_4 + 3H_2O ->\underset{\mathrm{ Sulphurous acid }}{ { H_2SO_3 }} + 4HCl} {SO_2 + H_2O ->\underset{\mathrm{ Sulphurous acid }}{ { H_2SO_4 }}}
