The reaction of phenol with sodium metal leads to the formation of biphenyl through the Wurtz reaction.

The formation of a peptide bond between two amino acids is a condensation reaction, releasing water.

Cross-linked polymers have a network structure due to the presence of covalent bonds between chains.

Most synthetic polymers can have linear, branched, or cross-linked structures depending on their synthesis.

Most thermoplastics have a linear or branched structure, allowing them to be remolded upon heating.

Butane is commonly used as a fuel in lighters.

Propane is commonly used as a refrigerant due to its favorable thermodynamic properties.

Ethylamine has the highest boiling point due to its ability to form stronger hydrogen bonds compared to the others.

Trimethylamine is known for its strong fishy odor, often associated with decaying fish.

Aniline is most likely to undergo electrophilic aromatic substitution due to the presence of the amino group, which is a strong activating group.

Methylamine is the most soluble in water due to its smaller size and ability to form hydrogen bonds.

Lidocaine is an amine used as a local anesthetic.

Triethylamine is commonly used as a solvent in organic reactions.
