Worked practice questions

Carbonyl carbon hybridization:

  1. sp³
  2. sp³d
  3. sp² (planar, 120° bond angles)
  4. sp
Show answer and solution

Correct answer: C. sp² (planar, 120° bond angles)

C=O is sp² (3 σ bonds + 1 π in C=O). Trigonal planar around C. Important for nucleophilic attack from above/below plane.

IUPAC name of CH₃CHO:

  1. Ethanal (acetaldehyde)
  2. Methanol
  3. Methanal
  4. Propanal
Show answer and solution

Correct answer: A. Ethanal (acetaldehyde)

CH₃CHO = ethanal (2-C aldehyde). **IUPAC:** replace -e of alkane with -al. HCHO = methanal (formaldehyde); CH₃CHO = ethanal.

As per your syllabus, reduction of an alkyne to a TRANS alkene uses which reagent system?

  1. Aqueous H₂SO₄
  2. Lindlar's catalyst
  3. Sodium in liquid ammonia
  4. H₂ / Pt at high pressure
Show answer and solution

Correct answer: C. Sodium in liquid ammonia

Your syllabus: Na/liq NH₃ gives trans alkene (via single-electron addition + vinyl radical inversion). Lindlar gives cis.
