One of the outstanding features of boron is its ability to form__________________?
Correct answer: A. Molecular addition compounds
- A. Molecular addition compounds
- B. Molecular crystals
- C. Semiconductors
- D. Ionic compounds
Explanation
Boron is electron deficient because it has only three valence electrons, so it readily forms electron-accepting molecular addition compounds such as boron halide adducts. The likely distractor is ionic compounds, but boron commonly forms covalent molecular compounds rather than simple ionic compounds.

About Reactions of Group IV Elements
Group IV, or Group 14, chemistry covers the trends from carbon and silicon to tin and lead, including their reactions with oxygen, halogens, water, acids and alkalis. It also examines the structures and properties of their oxides and chlorides, oxidation states, and the inert pair effect, rather than treating all members as equally metallic.
