Question

30) Arrange the compounds in a sequence of increasing number of oxygen atoms.

• A. 1243
• B. 2413
• C. 2314
• D. 2341

Answer 1

The correct option is B

2413

Explanation for the correct option -

(2) Plaster of Paris is represented by${\mathrm{CaSO}}_4.1/2{\mathrm{H}}_2\mathrm{O}$, here 4.5 oxygen atoms are present

(4) Glucose is represented by$\left({\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\right)$, here 6 oxygen atoms are present.

(1) Sugar is represented by$\left({\mathrm{C}}_{12}{\mathrm{H}}_{22}{\mathrm{O}}_{11}\right)$, here 11 oxygen atoms are present

(3) Starch is represented by${\left({\mathrm{C}}_6{\mathrm{H}}_{10}{\mathrm{O}}_5\right)}_{\mathrm{n}}$, here 5n oxygen atoms are present.

2413 is the correct order of increasing number of oxygen atoms.

Hence option ‘B’ is correct.
