B. heat always flows to the colder object to try to achieve equilibrium.
Sulfuric acid in an aqueous solution is substantially dissociated on ions.
B. H₂SO₄ + 2H₂O = 2H₃O⁺ + SO₄²⁻
Answer:
Chlorination of a 1° alcohol using Thionyl Chloride - an SN2 process
Alkene formation via POCl3 reaction with a 2º alcohol - an El process
Explanation:
For a primary alcohol, the chlorination occurs by SN2 mechanism. Remember that the order of SN2 mechanism is methyl > primary > secondary > tertiary. This means that a primary alkyl halide will undergo nucleophillic substitution by SN2 mechanism.
For a secondary alkyl halide, we normally expect that the mechanism will be E2. When we use POCl3 and pyridine, the alkyl halide passes through a carbocation intermediate which is characteristic of an E1 mechanism.
