Afeature of organic compounds not found in inorganic compounds is the presence of

(a) ionizing chemical groups
(b) electrons
(c) carbon atoms covalently bonded to each other
(d) oxygen
(e) hydrogen bonds

Organic and inorganic compounds are referred to as any substance that is chemically bonded. Organic compounds generally consist of carbon and hydrogen bonds.

Thus, the inorganic compounds do not have covalently linked carbon atoms.

The correct answer is Option C.

Carbon atoms covalently bonded to each other. (Ans C).

Explanation:

Organic compounds are different from inorganic compounds by the presence of carbon atom attached with other carbon atom or hydrogen atom. The simplest, and good example of organic compound is CH4. Some other atoms of organic compound also contains ring, and long chain of carbon atoms.

Other options are found in both organic, and inorganic compounds. So, the correct answer is option C.
