... F attracts electrons more than C in C-F bonds because the electronegativity of F (3.9) is much greater than that of C (2.5). In contrast, C-H bonds are not very polar because the electronegativities of H (2.3) and C (2.5) are about the same. Positive (+) values for the electronegativity differences ...

Inorganic chemistry
Inorganic chemistry deals with the synthesis and behavior of inorganic and organometallic compounds. This field covers all chemical compounds except the myriad organic compounds (carbon based compounds, usually containing C-H bonds), which are the subjects of organic chemistry. The distinction between the two disciplines is far from absolute, and there is much overlap, most importantly in the sub-discipline of organometallic chemistry. It has applications in every aspect of the chemical industry–including catalysis, materials science, pigments, surfactants, coatings, medicine, fuel, and agriculture.
