Chemistry · Chemical Bonding
Atoms form chemical bonds to attain stability by lowering their energy. Ionic bonds involve complete electron transfer, covalent bonds involve equal sharing, and coordinate bonds involve unequal sharing of electrons from one donor atom. According to valence bond theory, a covalent bond forms by the overlap of half-filled orbitals. Bond order affects bond length and bond strength — higher bond order = shorter, stronger bonds. Which of the following statements are correct? (A) CN− has higher bond order than NO and CN+. (B) Coordinate bond involves mutual sharing of electrons. (C) CsI3 contains Cs+ and I3− ions. (D) Repulsion between bond pairs is stronger than lone pairs.
