Organic compounds are primarily composed of carbon and hydrogen, often with other elements such as oxygen, nitrogen, sulfur, and halogens. The compound $\mathrm{C}_{4} \mathrm{H}_{8} \mathrm{O}$ contains carbon, hydrogen, and oxygen, which are typical elements found in organic compounds. Therefore, it is indeed an organic compound.
Inorganic compounds are generally not defined by the presence of carbon and hydrogen. Instead, they are typically composed of elements other than carbon and hydrogen, although there are exceptions like carbonates and cyanides. The statement that inorganic compounds are made mostly of carbon and hydrogen is incorrect.
Aside from carbon and hydrogen, organic compounds often contain elements such as oxygen, nitrogen, sulfur, and halogens (e.g., fluorine, chlorine, bromine, iodine). These elements are frequently involved in the structure and function of organic molecules.
$\mathrm{C}_{4} \mathrm{H}_{8} \mathrm{O}$ is an example of an organic compound because it is made of non-metals which could only make covalent bonds.
