Question

Electronegativity values vary depending on the chemical environment. Which of the following specific species or states have a strictly HIGHER electronegativity than a neutral Carbon atom in an $sp^3$ hybridized state?

Correct answer: A,B,C. Electronegativity increases with increasing s-character because s-orbitals are closer to the nucleus. Thus, . It also increases with a positive oxidation state (pulls electrons stronger). Silicon is directly below Carbon in Group 14, so it has a lower electronegativity than Carbon.
