Question

Match with O for organic and I for inorganic for each compound. NaS C3H6 SO2 HI C2H2

Answer 1

NAS-I

C3H6-O

SO2-I

HI-I

C2H2-O

Answer 2

The given compounds are matched with organic and inorganic compounds.

1.  NaS = I (inorganic)  

2.  $\mathrm{C}_{3} \mathrm{H}_{6}$ = O (organic)

3. $\mathrm{SO}_{2}$ = I (inorganic)

4. HI = I (inorganic)

5.  $\mathrm{C}_{2} \mathrm{H}_{2}$ = O (organic)

Here the simple concept is that the organic compounds can be defined as the compound with C atom in the molecule. Here C is the atomic symbol of carbon atom. All other compounds without C atom are called as inorganic compounds.
