Worked practice questions

As per your syllabus, the first step in naming a branched alkane is to identify which feature?

  1. Most branched carbon
  2. Heaviest substituent
  3. Smallest carbon chain
  4. Longest carbon chain
Show answer and solution

Correct answer: D. Longest carbon chain

syllabus rule 1: select the longest continuous chain as the parent (gives lowest locants to substituents).

As per your syllabus, example, CH₃-CO-CH₂-CH₂-CH₂-COOH is named as which?

  1. 2-Oxohexanoic acid
  2. 6-Oxohexan-1-oic acid
  3. 5-Oxohexanoic acid
  4. 5-Oxopentanoic acid
Show answer and solution

Correct answer: C. 5-Oxohexanoic acid

syllabus Problem 8.8(iii): COOH = principal FG (C1), keto at C5 ⇒ 5-oxohexanoic acid chain has 6 carbons.

As per your syllabus, the inductive effect typically becomes vanishingly small after how many intervening bonds?

  1. 1 bond
  2. Always strong
  3. 3 bonds
  4. 6 bonds
Show answer and solution

Correct answer: C. 3 bonds

Your syllabus: I-effect drops sharply and is negligible beyond 3 σ-bonds.
