Detailed Question-by-Question Analysis

Chemistry Questions 46-50

Question 46: Organic Compound Conversion

The question asked to identify a suitable reagent for converting a methoxy compound to an aldehyde, with option 4 (AlH(iBu)₂, then H₂O) marked as correct.

Conceptual Match: Our prediction file contained similar organic chemistry conversion questions, particularly those asking about the transformation of organic compounds. While there wasn't an exact match with this specific reagent, we did predict questions about aldehyde conversions.

Question 47: Acid Strength Comparison

Question about the correct order of decreasing acidity of aliphatic acids, with option 1 (HCOOH > CH₃COOH > (CH₃)₂CHCOOH > (CH₃)₃CCOOH) marked as correct.

Conceptual Match: Our prediction file contained multiple questions about acid-base properties and reactions. We had predicted questions about acid strength comparisons, although not with this exact sequence of compounds.

Question 48: Lassaigne's Test

Question about which reaction does NOT belong to "Lassaigne's test," with option 2 (2CuO + C → 2Cu + CO₂) marked as correct.

No Direct Match: No direct match for Lassaigne's test questions in our predictions.

Question 49: Reaction Rate Calculation

Question about rate constant and reaction time calculations, with option 3 (69.3 s) marked as correct.

Conceptual Match: Our predictions included several calculation-based questions, including those on equilibrium constants and reaction rates, showing conceptual coverage of this topic area.

Question 50: Diatomic Molecule Properties

Question involving statements about diatomic molecules with bond order zero and bond length increases, with option 4 (Both statements false) marked as correct.

Partial Match: Our predictions included questions about molecular properties and bond characteristics, though not with this exact formulation.

Chemistry Questions 51-55

Question 51: Complex Compound Conductance

Question about which complex compound has minimum conductance in solution, with option 3 ([Co(NH₃)₃Cl₃]) marked.

Conceptual Match: Our predictions included questions about complex compounds and their properties, showing conceptual coverage.

Question 67: Equilibrium Constants

Question about reaction equilibrium constants, with option 1 (0.033) marked.

Direct Match: Our predictions included numerous questions about equilibrium constants (Kc, Kp), making this a strong conceptual match. We predicted several questions with the format 2A(g) + B(g) → 2C(g) and calculations involving equilibrium constants.

Question 72: Paramagnetic Compounds

Question about which compounds are paramagnetic, with option 1 (A and D only) marked.

Direct Match: Our predictions included multiple questions of the exact form "Which of the following compounds will exhibit paramagnetic behavior and why?" making this a direct match. This type of question appeared several times in our prediction file.

Question 82: Reaction Product Identification

Question about predicting the major product in a sequence of reactions, with option 3 marked.

Direct Match: Our predictions included numerous questions about identifying products of reactions, making this a good conceptual match. We had multiple questions with the format "Identify the product(s) of the following reaction..."

Sodium-Chlorine Reaction

Multiple questions throughout the exam regarding the reaction 2Na + Cl₂ → 2NaCl and calculations based on this reaction.

Direct Match: Our predictions included multiple questions specifically about this reaction, including calculations of mass, moles, and balancing the equation, providing a direct match to several exam questions.
