Question

Which of the following reagents does not give oxygen as one of the product during oxidation with ozone.

• A. $Hg$
• B. $S{O}_2$
• C. $SnC{l}_2/HCl$
• D. $H_{2}S$

Answer 1

Answer: (B), (C)

$2Hg+O_3\to H{g}_{2}O+O_2$

$3S{O}_2+O3\to 3S{O}_3$

$3SnC{l}_2+6HCl+O_3\to 3SnC{l}_4+3H_{2}O$

$H_{2}S+O_3\to S+O_2+H_{2}O$

Hence options B & C are correct.
