What is the pH of a solution with a hydrogen ion concentration of 1×10⁻⁴ M?
Answer: 4
pH = −log[H⁺] = −log(1×10⁻⁴) = 4.
According to the Brønsted-Lowry definition, an acid is a substance that:
Answer: Donates protons (H⁺)
A Brønsted-Lowry acid donates a proton (H⁺) to another substance.
What organic product is formed when a carboxylic acid reacts with an alcohol?
Answer: Ester
Esterification occurs when a carboxylic acid reacts with an alcohol, producing an ester and water.
Which functional group characterizes alcohols?
Answer: −OH (hydroxyl)
Alcohols are defined by the hydroxyl (−OH) group bonded to a carbon atom.
What is the IUPAC name for the straight-chain alkane with the molecular formula C₃H₈?
Answer: Propane
C₃H₈ has three carbon atoms, corresponding to the 'prop-' prefix, making it propane.
What products form when hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH) in a neutralization reaction?
Answer: NaCl and H₂O
HCl + NaOH → NaCl + H₂O; a strong acid and strong base neutralize each other to form a salt and water.
What is the hybridization of each carbon atom in ethylene (C₂H₄)?
Answer: sp²
Each carbon in ethylene is sp² hybridized, forming a double bond (one σ bond from sp² orbitals and one π bond from unhybridized p orbitals).
