(a)
Interpretation:
The structure of the product for the given reaction should be determined.
Concept introduction:
The halogenation of
In the halogenation reaction, inert solvents such as
A nucleophile is the Lewis base that donates a pair of an electron to form a covalent bond with the electrophile. An electrophile is the Lewis acid that accepts the electron to form a bond with the nucleophile.
(b)
Interpretation:
The structure of the product for the given reaction should be determined.
Concept introduction:
Reaction of alkenes with hydrogen halide is an example of an addition reaction. In this reaction, halogen and hydrogen atom adds across the carbon-carbon double bond to give a saturated compound.
(c)
Interpretation:
The structures of the product for the given reaction should be determined.
Concept introduction:
The addition on the alkene is the electrophilic addition reaction. In this reaction, electrophile reacts with carbon-carbon double of the alkene which results in the formation of
The addition of water to the alkene in the presence of strong acid which results in the formation of alcohol. This is the type of hydration of alkene.
A nucleophile is the Lewis base that donates a pair of an electron to form a covalent bond with the electrophile. An electrophile is the Lewis acid that accepts the electron to form a bond with the nucleophile.

- Determine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR.
