Let's analyze each reaction to identify its type.
1. First Reaction:
[tex]\[(CH_3)_3COH + CH_3OH \rightarrow (CH_3)_3COCH_3 + H_2O\][/tex]
In this reaction, two molecules combine to form a larger molecule with the elimination of a water molecule. This type of reaction is known as a condensation reaction because it results in the formation of a larger molecule with the loss of a smaller molecule (water).
2. Second Reaction:
[tex]\[H_3CCH=CHCH_3 + HBr \rightarrow CH_3CH_2CH(Br)CH_3\][/tex]
This reaction involves the addition of HBr across the double bond of an alkene, converting it into a bromoalkane. This type of reaction is known as an addition reaction because the reactants combine to form a single product without the loss of any atoms.
3. Third Reaction:
[tex]\[(CH_3)_3COH \rightarrow CH_3CH_3C_2H_2 + H_2O + Br_2\][/tex]
Although the specific molecules involved are not clearly represented in the equation, the reaction involves the elimination of small molecules such as water and potentially another molecule (like Bromine or a hydrocarbon fragment). This type of reaction is commonly known as an elimination reaction because it involves the removal (or elimination) of small molecules from the reactant.
So, the classifications for each reaction type are:
1. Condensation
2. Addition
3. Elimination
