Discover why the $\text{NH}_2$ group is highly polar, focusing on the role of nitrogen's lone pair and molecular asymmetry in creating a strong dipole.
Explore the fundamental structural difference between $\text{CH}_4$ and $\text{NH}_3$ that dictates their unique geometry, polarity, and behavior in nature.
We confirm polyester is a polymer and explain the defining chemical structure. Understand the ester linkage, condensation polymerization, and its classification.
