Question

Chitin present in fungal wall has a formula

• A. $(C_{22}{H}_{54}{N}_4{O}_{21}{)}_n$
• B. $(C_{21}{H}_{54}{N}_4{O}_{22}{)}_n$
• C. $(C_{22}{H}_{54}{N}_4{O}_{13}{)}_n$
• D. $(C_{22}{H}_{24}{N}_4{O}_{21}{)}_n$

Answer 1

The correct option is A $(C_{22}{H}_{54}{N}_4{O}_{21}{)}_n$

Chitin has formula (C${}_{22}$H${}_{54}$N${}_4$O${}_{21}$)${}_n$ and is present in fungal wall.
Chitin is the second most abundant organic compound found in nature, has long chain polysaccharides with its base unit as amino sugar.

Thus, the correct answer is option A.
