Chemistry Cumulative Final Exam Questions and Answers Already Passed What feature makes carbon exceptionally distinct among elements? Carbon can form a wide range of structures, including linear chains, branched chains, and rings, more extensively than other elements. - Carbon exists in two distinct allotropes: diamond and graphite. - Despite its ground state configuration, carbon forms four bonds. - Carbon generally forms covalent bonds instead of ionic ones. - Carbon has stable isotopes: carbon-12 and carbon-13. Which statement does NOT describe a physical property of alcohols or phenols? The hydroxyl group in alcohols is nonpolar. - Phenols generally have limited solubility in water. - The solubility of normal primary alcohols in water decreases with increasing molecular size. - Alcohols have higher boiling points compared to similar alkanes due to hydrogen bonding. - Boiling points of primary alcohols increase with larger molecular weights. Which of the following is NOT typically associated with acids? 2 It has a soapy texture. - It changes litmus paper to pink or red. - It reacts with common metals. - All of the above are characteristics of acids. If the equilibrium constant, Keq, is greater than 1, what can be concluded about the system at equilibrium? The amount of products exceeds that of the reactants. - There are more reactants present than products. - The concentrations of products and reactants are equal. - The relative composition of the reaction mixture remains unpredictable. What defines a weak acid? It partially ionizes in water, forming a mixture of molecules and some ions. - It does not dissolve in water. - It completely ionizes in water, producing only ions. - It dissolves in water solely as molecules.
