Worked practice questions
Grignard reagent: R-X + Mg in dry ether gives:
- R-OH
- R-Mg-X (organomagnesium halide; powerful nucleophile/base)
- R-Cl
- No reaction
Show answer and solution
Correct answer: B. R-Mg-X (organomagnesium halide; powerful nucleophile/base)
**Grignard reagent:** R-MgX. Forms in dry ether.
Carbon is δ-, magnesium δ+.
Acts as carbanion equivalent.
Reacts with H₂O (destroys reagent: → R-H), CO₂ (→ RCOOH), carbonyls (→ alcohols).
As per your syllabus, (ii), the Wurtz reaction uses which reagent + solvent for coupling alkyl halides?
- NaOH and CaO
- Zinc in dilute HCl
- Pt or Pd catalyst
- Sodium in dry ether
Show answer and solution
Correct answer: D. Sodium in dry ether
Your syllabus: Wurtz: 2 R-X + 2 Na → R-R + 2 NaX in dry ether.
Used to make higher alkanes with even carbon count.
