Answer
EXAMINATION INSTRUCTIONS
▸ Select the single best answer for each question.
▸ Content covers: ionic vs. covalent bonding, chemical nomenclature (ionic compounds, molecular compounds, acids),
electronegativity trends, formal charge, VSEPR theory (electron-domain and molecular geometry for 2–6 domains),
hybridization (sp through sp³d²), sigma/pi bonds, and bond angles.
▸ Each question includes the correct answer with a detailed rationale.
SECTION I — COMPREHENSIVE EXAM 2 Questions 1 – 20
1. An ionic bond is formed between:
A. Two nonmetals
B. A metal and a nonmetal
C. Two metals
D. Two noble gases
CORRECT ANSWER B — A metal and a nonmetal
RATIONALE IONIC bonds form between a METAL and a NONMETAL — electrons are TRANSFERRED. COVALENT bonds form
between TWO NONMETALS — electrons are SHARED. Naming ionic compounds: name the cation (metal), then
the anion (nonmetal) with "-ide." Common cations: Na⁺ (sodium), Li⁺ (lithium), K⁺ (potassium), Ca²⁺ (calcium),
Mg²⁺ (magnesium), Cs⁺ (cesium), Al³⁺ (aluminum), Ba²⁺ (barium), Sr²⁺ (strontium). Common anions: Br⁻
(bromide), Cl⁻ (chloride), I⁻ (iodide), F⁻ (fluoride), O²⁻ (oxide), S²⁻ (sulfide), N³⁻ (nitride), P³⁻ (phosphide), Se²⁻
(selenide). Naming molecular compounds: Greek prefixes for both elements, second gets "-ide" (omit "mono"
on first).
