1. the monomer used as the building block in polyethylene is __. (1 point)
b. (1 point) ethene
2. What happens in a condensation reaction?
a. (1 point) head-to-tail joining of monomers
2/2 points 100%
Here's a head-to-tail condensation I remember from my Grad School days; but after this, you'll have to entertain contributions from others...
Bis-Phthaloyl Chloride + Ethylene Glycol (typically in an aprotic solvent) => Polyphthaloylethylene Glycol Ester (a Polyester) + HCl
Cl-CO-(C6H4(ring))-CO-Cl + HOCH2CH2OH => ---HO-CH2CH2O-[-CO-(C6H4)-CO-OCH2CH2O-]-... + HCl
As I recall this is referred to as a nucleophilic condensation with HCl

As I recall this is referred to as a nucleophilic condensation with HCl as by-product.

thank youuuu 100%
In a condensation reaction, which is a type of chemical reaction, two or more molecules combine to form a larger molecule while releasing a smaller molecule, typically water.
There are different outcomes that can happen in a condensation reaction:
1. Head-to-tail joining of monomers: This occurs when the monomers (smaller building blocks) join together in a linear fashion, with one monomer attaching to the end of another, like a chain. This type of joining often occurs in the formation of polymers such as proteins.
2. Side-by-side joining of monomers: This happens when the monomers join together next to each other, forming a larger molecule with a repeating pattern along its length. This type of joining is typical in the formation of polymers such as nucleic acids (DNA and RNA).
3. Cross-linking of monomers: In some cases, the monomers can form connections not only with their neighboring monomers but also with monomers that are nearby, forming a network-like structure. This process is called cross-linking, and it is commonly seen in the formation of certain polymers like rubber or the hardening of thermosetting plastics.
4. Substitution of halogen: This is not typically associated with a condensation reaction. Substitution of halogens refers to the replacement of a halogen atom in a molecule with another atom or group of atoms. This is a different type of reaction known as a substitution reaction.
To understand which outcome occurs in a specific condensation reaction, one needs to consider the nature of the monomers involved, the reaction conditions, and the specific mechanism of the reaction.
