Answer:
The small molecule produced in this condensation reaction is water.
Formula of the compound is given by [tex][C_{12} H_{22}N_{2}O_{2}]_{n}[/tex]
Explanation:
Nylon is a poly amide which is formed by the condensation reaction between adipic acid and hexamethylenediamine.
A reaction is called a condensation reaction when it involves removal of small molecules like water to form product.
In this condensation reaction a molecule of water is removed between the monomers to form a repeating unit of polymer. This process is clearly explained by the figure below.
We can see that the -OH group from the acid and -H atom from amine is removed to form a -CONH- group known as amide group.In effect a water molecule is removed in the formation of Nylon-6,6.
Since the monomers are connected by an amide group the polymer thus formed is a poly amide .We can see from the attachment that the formula of the polymer formed is [tex][C_{12}H_{22}N_{2}O_{2}]_{n}[/tex].
In the condensation reaction, the small molecule produced is water and the formula for the compound will be [tex]\rm [C_{12}H_{22}N_{2}O_{2}]_{n}[/tex].
A chemical reaction in which the two or more molecules combines to form a single product is called a condensation reaction. Nylon is a product of such condensation reaction and is formed when adipic acid and hexamethylenediamine reacts.
For the formation of the polymer, the water from the repeating monomer unit is shown in the attached image below.
For the formation of the amide group, [tex]\rm (-CONH-)[/tex] the hydroxide group [tex]\rm (-OH)[/tex] from the acid and the hydrogen atom [tex]\rm ( -H )[/tex]from the amine gets removed. This results in the removal of the water molecule and the Nylon-6,6 is formed.
Therefore, the polymer has a formula of [tex]\rm [C_{12}H_{22}N_{2}O_{2}]_{n}[/tex].
