Organic chemistry is the branch of chemistry that deals with the study of carbon-containing compounds.

• Focuses on the structure, properties, composition, reactions, and synthesis of carbon-based compounds

• Includes the study of hydrocarbons, alcohols, acids, esters, and more

• Important in pharmaceuticals, petrochemicals, plastics, and other industries

Inorganic chemistry is the branch of chemistry that deals with the study of inorganic compounds, which do not contain carbon-hydrogen bonds.

• Focuses on elements other than carbon

• Studies properties and behavior of inorganic compounds

• Includes metals, minerals, and non-carbon containing compounds

• Examines reactions and synthesis of inorganic substances

Ammonia reacts with acids to form ammonium salts, with metals to form amides, and with halogens to form salts.

• Ammonia reacts with acids to form ammonium salts (e.g. NH3 + HCl -> NH4Cl)

• Ammonia reacts with metals to form amides (e.g. 2NH3 + 2Na -> 2NaNH2 + H2)

• Ammonia reacts with halogens to form salts (e.g. NH3 + HCl -> NH4Cl)

Chemical names are unique identifiers for specific substances used in chemistry.

• Chemical names can be systematic (following specific rules) or common (based on historical usage)

• Examples of chemical names include: sodium chloride, hydrogen peroxide, sulfuric acid
