If Cell-OH represents formula of cellulose, identify the formula of cellulose xanthate from following.

• A

  Cell-ONa
• Correct answer
  B

  \(\mathrm{Cell}-\mathrm{O}-\underset{|| \atop \large \mathrm{S}}{\mathrm{C}}-\mathrm{SNa}\)
• C

  \(\mathrm{Cell}-\mathrm{O}-\underset{|| \atop \large \mathrm{S}}{\mathrm{C}}-\mathrm{SH}\)
• D

  \(\mathrm{Cell}-\mathrm{O}-\underset{|| \atop \large \mathrm{S}}{\mathrm{C}}-\mathrm{OH}\)

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