MCAT - ORGANIC CHEMISTRY EXAM-90 QUESTIONS & ANSWERS 2025

MCAT Chem/PhysGenerally, how are proteins formed? The connecting of a string of amino acids via peptide bonds and the folding of this string to create a completed protein. The folding is determined primarily by the hydrophilic and/or hydrophobic nature of the amino acids. Stabilized by hydrogen bonds, disulfide bridges, and other intramolecular forces. Peptide (Amide) Bonds These are formed when the n-terminus of one amino acid attacks the carboxy terminus of another amino acid. Water is ...

MCAT Organic Chemistry Written Exam. Electrostatic Forces - CORRECT ANSWER The attractive force between electrons and the nuclei that is responsible for all molecular bonds. Coordinate Covalent Bond - CORRECT ANSWER One nucleus donates both of the electrons in the bond. Hybridization - CORRECT ANSWER sp - 180° - linear sp2 - 120° - trigonal planar sp3 - 109.5° - tetrahedral, pyramidal, or bent dsp3 - 90°, 120° - trigonal-bipyramidal, seesaw, t-shaped, linear d2sp3 - 9...

Further oxidation yields a carboxylic acid. What is the primary reagent used for the reduction of ketones to secondary alcohols? The primary reagent is sodium borohydride (NaBH4) or lithium aluminum hydride (LiAlH4). What is the characteristic reaction of a carboxylic acid with an amine? The reaction ...

MCAT - General Chemistry Questions and Answers | Latest Version | 2024/2025 | 100% Pass What is the definition of an isotope? An isotope is a variant of an element that has the same number of protons but a different number of neutrons in its nucleus. What does the term "electronegativity" refer to? Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond. What is the principle behind the concept of "Le Chatelier's Princip...

MCAT Organic Chemistry Questions and Answers | Latest Update | 2024/2025 | 100% Verified What is the typical product of a Friedel-Crafts alkylation reaction? The typical product of a Friedel-Crafts alkylation reaction is an alkyl-substituted benzene. How does the inductive effect influence the acidity of a carboxylic acid? The inductive effect of electronegative substituents increases the acidity of a carboxylic acid by stabilizing the carboxylate anion formed after deprotonatio...

MCAT AAMC practice exam Chemistry and Physics Comprehensive Review

MCAT General Chemistry | Latest Update | 2024/2025 | Already Passed What is the role of the conjugate base in an acid-base reaction, and how does it influence the reaction equilibrium? The conjugate base is formed when an acid donates a proton. It influences the reaction equilibrium by interacting with the acid, shifting the equilibrium based on the relative strengths of the acid and its conjugate base. How does the presence of a common ion affect the solubility of a salt in a solu...
