Question

1. C3N2H4 2. AIBr3 3. C6H5F 4. CrO3 5. H2O2 6.C12H22O11

Answer 1

A. Organic compounds - C₃N₂H₄ , C₆H₅F and C₁₂H₂₂O₁₁

Organic compounds are compounds which have Carbon except few compounds such as carbon dioxide, cyanide. Other than Carbon, other elements also present such as Hydrogen, Oxygen and Nitrogen. But Carbon is considered as the main element of organic compounds. 

B. Inorganic substances - AIBr₃ , CrO₃ and H₂O₂

Inorganic substances are the compounds which do not own C-H bonds. Most inorganic compounds do not have carbon as their element except few. (Cyanides, carbon dioxide, carbon monoxide and so on are considered as inorganic although they have carbon).
