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.
The polarity of the molecules determines the forces of attraction between the molecules in the liquid state. Polar molecules are attracted by the opposite charge effect (the positive end of one molecule is attracted to the negative end of another molecule. Molecules have different degrees of polarity as determined by the functional group present.
<span>Principle: The greater the forces of attraction the higher the boiling point or the greater the polarity the higher the boiling point.</span>
The Number of moles required for MTBE is 2 as per molarity based chemistry theories.
- A flammable liquid with a distinct, unpleasant smell is called methyl tert-butyl ether (MTBE).
- Since the 1980s, it has been added to unleaded gasoline as a fuel additive to promote more effective burning.
- It is created by mixing chemicals like isobutylene and methanol. Gallstones can be removed with MTBE as well.
- In this type of treatment, surgically inserted special tubes are used to deliver MTBE directly to the gall bladders of the patients.
- Methyl tert-butyl ether is a colorless liquid with a distinct anesthetic-like smell. Vapors are narcotic and heavier than air. 131 °F boiling point. 18 °F is the flash point.
- It is miscible in water and less dense than water. Boosts the octane of gasoline.
- Therefore it has 2 moles of oxygen.

Answer:
The acid dissociation constant, also called the acid-ionization constant, represents the <u>equilibrium constant</u> of a given chemical reaction, which is denoted by the symbol Ka.
It gives the measure of the<u> acidic strength </u>of a chemical substance or the <u>dissociation of an acid</u> in a solution and is represented as the ratio of concentrations of product and the reactants, at equilibrium.
