As per your syllabus, the general formula of an alkane (saturated open-chain hydrocarbon) is which?

  1. CₙHₙ
  2. CₙH₂ₙ₊₂
  3. CₙH₂ₙ₋₂
  4. CₙH₂ₙ
Show answer and solution

Correct answer: B. CₙH₂ₙ₊₂

Your syllabus: alkanes follow CₙH₂ₙ₊₂. Alkenes are CₙH₂ₙ; alkynes CₙH₂ₙ₋₂.

As per your syllabus, Friedel-Crafts ALKYLATION of benzene uses which reagent system?

  1. R-Cl with anhydrous AlCl₃
  2. R-Cl with Na in dry ether
  3. ROH with conc. H₂SO₄
  4. R-COOH with NaOH/CaO
Show answer and solution

Correct answer: A. R-Cl with anhydrous AlCl₃

Your syllabus: alkyl halide + anhydrous AlCl₃ generates R⁺, which attacks benzene to form alkylbenzene.
