Instructions and Examination Rules

This assessment evaluates knowledge and application of undergraduate-level general chemistry topics relevant to BMAT preparation. Total time allowed: 90 minutes. Write legibly in ink. Calculators are permitted only where stated on individual questions. All work must be the candidate's own. Any assistance from others or use of unauthorized materials is a breach of assessment regulations and may result in a failing grade, disqualification of results, and other disciplinary measures.

Clearly show all working for calculation-based questions. Where a final numerical answer is required, circle or underline the value. Units must be provided where applicable. Answers without supporting working may receive reduced credit.

Accommodations

The institution provides approved assessment accommodations for qualified candidates. Indicate any approved accommodations in effect for this administration:

  Extra time (specify minutes):

  Reader provided

  Scribe allowed

If other accommodation, describe:

Part I — Short Response (Answer all questions)

1. Balance the following equation and state the physical states: C2H5OH + O2 → CO2 + H2O. Balanced equation:

2. Identify the reagent(s) required to selectively oxidize a primary alcohol to an aldehyde without further oxidation to a carboxylic acid.

3. A 0.100 mol sample of solute is dissolved in 0.500 L of solution. Calculate the molarity (to three significant figures).

4. Determine the pH of a 0.01 M solution of a weak acid HA with Ka = 1.0 x 10^-5. Final pH:

5. Provide the major organic product and brief mechanistic rationale for the acid-catalyzed dehydration of 2-butanol.

6. Given an IR peak at ~1715 cm^-1 and a singlet at δ 9.8 ppm in the 1H NMR, propose a likely functional group and one plausible compound.

Part II — Extended Response (Show full analysis)

7. A reaction yields 72.0 g of product when 100.0 g of limiting reagent A (molar mass 120.0 g/mol) is reacted under the stated conditions. Calculate percent yield and discuss two experimental factors that could reduce yield. Show calculations and discussion.

8. Describe an experimental procedure to determine the rate law for the reaction A + B → products using initial rates. Include the measurements required and how orders with respect to A and B would be deduced.

Practical Observations (If applicable)

Record brief observations from any practical component conducted as part of this assessment (color changes, precipitates, gas evolution, temperatures, times). Document any deviations from the protocol below.

Scoring and Examiner Use

Examiner to record raw scores for each part and total. Scores are subject to moderation per departmental policy.
