Inorganic chemistry is a branch of chemistry that studies the properties, behavior, and synthesis of inorganic compounds. Inorganic compounds are those that do not contain carbon-hydrogen (C-H) bonds. This means that inorganic chemistry excludes organic compounds, which are those that do contain C-H bonds.

Organic chemistry, on the other hand, is the branch of chemistry that studies the properties, behavior, and synthesis of organic compounds. Organic compounds are those that contain carbon-hydrogen bonds. This includes a wide range of compounds, including hydrocarbons, alcohols, aldehydes, ketones, carboxylic acids, and more.

Therefore, inorganic chemistry does not focus on the compounds which contain c-h bonds.
