In the extraction of copper from copper glance, blister copper is formed by the evolution of gas $\underline{X}$. The shape of molecule of $\underline{X}$ is

• Correct answer
  A

  Angular
• B

  Plánar trigonal
• C

  Tetrahedral
• D

  Pyramidal

Solution

$2 \mathrm{Cu}_2 \mathrm{~S}+3 \mathrm{O}_2 \rightarrow 2 \mathrm{Cu}_2 \mathrm{O}+2 \mathrm{SO}_2$ $$ 2 \mathrm{Cu}_2 \mathrm{O}+\mathrm{Cu}_2 \mathrm{~S} \rightarrow 6 \mathrm{Cu}+\mathrm{SO}_2 $$ Shape of $\mathrm{SO}_2=$ Angular $/$ bent

Hence, the correct answer is option: 'A'.
