Classify each compound as organic or inorganic: a. C8H18 b. CH3NH2 c. CaO d. FeCO3

Verified step by step guidance

Identify the general characteristics of organic compounds, which typically contain carbon and hydrogen, often with C-H bonds.

Recognize that inorganic compounds generally do not have C-H bonds and may include metals, salts, and minerals.

Examine compound a, C8H18: It contains only carbon and hydrogen, indicating it is an organic compound.

Examine compound b, CH3NH2: It contains carbon and hydrogen, along with nitrogen, indicating it is an organic compound.

Examine compounds c, CaO, and d, FeCO3: Both contain metals (calcium and iron, respectively) and do not have C-H bonds, indicating they are inorganic compounds.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Organic Compounds

Organic compounds are primarily composed of carbon atoms, often in combination with hydrogen, oxygen, nitrogen, and other elements. They typically contain carbon-hydrogen (C-H) bonds and are associated with living organisms. Common examples include hydrocarbons, alcohols, and amino acids.

Inorganic Compounds

Inorganic compounds generally do not contain carbon-hydrogen bonds and include a wide range of substances such as minerals, metals, and salts. They can be composed of metals, nonmetals, and metalloids, and often play crucial roles in various chemical processes and reactions.

Classification Criteria

The classification of compounds as organic or inorganic is based on their molecular structure and composition. Organic compounds typically contain carbon and are associated with biological processes, while inorganic compounds encompass a broader range of substances that do not fit this definition. Understanding these criteria is essential for accurate classification.
