reactants and products

LAB 2 — Acidification of Sodium Benzoate

Reactant(s):

• Sodium benzoate (C₆H₅COO⁻ Na⁺)

• Hydrochloric acid (HCl)

• Water (solvent)

Product(s):

• Benzoic acid (solid) ← MAIN PRODUCT

• NaCl (aqueous)

LAB 3 — Acid–Base Extraction

Reactant(s) (the mixture you start with):

• Benzoic acid

• 2-naphthol

• Naphthalene

• Diethyl ether (organic solvent)

Reagents added:

• Sodium bicarbonate (NaHCO₃)

• Sodium hydroxide (NaOH)

• Hydrochloric acid (HCl)

• Product(s):

  You end with three separate purified solids:

  • Benzoic acid (re-acidified from NaHCO₃ extract)

  • 2-naphthol (re-acidified from NaOH extract)

  • Naphthalene (already neutral, isolated from organic layer)

LAB 5 — Distillation of Unknown Liquid

Reactant(s):

• A liquid mixture (two miscible organic liquids)

Product(s):

• Lower-boiling liquid distillate (the purified component)

• Higher-boiling component stays in flask

You also identify the product using density + boiling point.

LAB 8 — Hydrolysis of Methyl Salicylate → Salicylic Acid

Reactant(s):

• Methyl salicylate

• Sodium hydroxide (NaOH)

• Water

Product(s):

• Salicylic acid (solid) ← MAIN PRODUCT

• Methanol (from ester hydrolysis)

(You re-protonate salicylate with H₂SO₄ to get the solid.)

LAB 9 — Dehydration of Cyclohexanol → CyclohexeneReactant(s)

• Cyclohexanol

• Phosphoric acid / sulfuric acid (acid catalyst)

Product(s):

• Cyclohexene ← MAIN PRODUCT (distilled off)

• Water (by-product)

This is an E1 elimination.

LAB 10 — SN1 Synthesis of tert-Pentyl Chloride

Reactant(s):

• tert-Pentyl alcohol (2-methyl-2-butanol)

• Hydrochloric acid (HCl)

Product(s):

• tert-Pentyl chloride (organic layer) ← MAIN PRODUCT

• Water (by-product)

This is an SN1 reaction.
