 compound A (C₃H₆O):

  • Gives a positive 2,4-DNP test
  • Does not react with Tollens’ reagent
  • Reacts with HCN to form a chiral product

Question

Identify:

  1. The name and structure of A
  2. The functional group
  3. The name of the reaction with HCN
  4. Why the product is chiral

One-line answers

  1. A: propanone (CH₃COCH₃)
  2. Functional group: ketone
  3. Reaction with HCN: nucleophilic addition
  4. Why chiral: forms a new stereocentre (C bonded to –OH, –CN, and two different groups)

🔥 “Impossible” Mod 7 Organic Chemistry Question

A compound A has molecular formula C₅H₁₀O₂.

Part A

Compound A reacts with Na₂CO₃ to produce effervescence.
When A is heated under reflux with ethanol and concentrated H₂SO₄, compound B is formed.

Identify:

  • Functional group in A
  • Structure of A (draw/displayed formula)

Part B

Compound B is heated with aqueous NaOH.

  • Name the reaction type
  • Identify the organic product C

Part C

Compound A is reduced using LiAlH₄ to form compound D.

  • Identify functional group of D
  • Draw structure of D

Part D

Compound D is oxidised using acidified K₂Cr₂O₇ under reflux to form compound E.

  • Identify E
  • Explain why reflux is required

Part E (isomer nightmare)

Draw and name ALL structural isomers of A that:

  • Have the same molecular formula
  • React with Na₂CO₃
  • Can form esters

Part F (synthesis pathway — killer)

Design a synthesis pathway to convert:
but-1-ene → compound A

Include:

  • Reagents
  • Conditions
  • Intermediate structures

💀 Why this is “impossible”

You must combine:

  • Functional group tests
  • Esterification + hydrolysis
  • Oxidation/reduction pathways
  • Isomer identification
  • Organic synthesis design

Part A

  • Functional group: carboxylic acid (–COOH)
  • Structure of A: pentanoic acid (CH₃CH₂CH₂CH₂COOH)

Part B

  • Reaction type: ester hydrolysis (saponification)
  • Product C: sodium pentanoate (CH₃CH₂CH₂CH₂COO⁻ Na⁺)

Part C

  • Functional group of D: primary alcohol
  • D: pentan-1-ol (CH₃CH₂CH₂CH₂CH₂OH)

Part D

  • E: pentanoic acid
  • Reflux reason: ensures complete oxidation by preventing loss of volatile intermediates

Part E

Isomers (must be carboxylic acids):

  • pentanoic acid
  • 2-methylbutanoic acid
  • 3-methylbutanoic acid
  • 2,2-dimethylpropanoic acid

Part F (pathway)

but-1-ene → pentan-1-ol → pentanoic acid

Reagents:

  1. Hydroboration-oxidation (BH₃ / H₂O₂, OH⁻)
  2. Oxidation (K₂Cr₂O₇ / H⁺, reflux)

If you want, I can give you the 1-step trick to identify A instantly in exams (it saves like 2–3 minutes).
