Polymers concept questions and answers

What are polymers? Polymers are large molecules made up of repeating subunits known as monomers. These monomers are covalently bonded to each other in a chain-like structure. What is the difference between a monomer and a polymer? A monomer is a single, small molecule that may become chemically bonded to other monomers to form a … Read more

Isomers concept questions and answers

What are isomers? Isomers are molecules that have the same molecular formula, but different structural formulas. They possess the same number of atoms of each element but exhibit different arrangements of these atoms in space. What are the main types of isomerism? The main types of isomerism are structural (or constitutional) isomerism and stereoisomerism. Structural … Read more

Alkane derivatives concept questions and answers

What are alkane derivatives? Alkane derivatives, also known as substituents or functional groups, are compounds that have the same structure as an alkane but with one or more hydrogen atoms replaced by different atoms or groups of atoms. Examples include alcohols, ethers, amines, and halocarbons. What is an alcohol? An alcohol is an organic compound … Read more

Benzene concept questions and answers

What is benzene? Benzene (C₆H₆) is an organic chemical compound and one of the fundamental structures in chemistry. It is an aromatic hydrocarbon that consists of six carbon atoms joined in a ring, with one hydrogen atom attached to each carbon. What is the structure of benzene? Benzene has a planar hexagonal ring structure (a … Read more

Noble gases concept questions and answers

What are noble gases? Noble gases are elements found in Group 18 of the periodic table. They include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). They are characterized by their full valence electron shells which make them very stable and unreactive. Why are noble gases unreactive? Noble gases are … Read more

Alkali metals and alkaline earths concept questions and answers

What are alkali metals? Alkali metals are elements located in Group 1 of the periodic table, excluding hydrogen. They include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). They are known for their high reactivity due to their single valence electron. What are alkaline earth metals? Alkaline earth metals are … Read more

Elemental chemistry concept questions and answers

What is the Periodic Table of Elements? The Periodic Table of Elements is a tabular arrangement of chemical elements, organized based on their atomic number, electron configuration, and recurring chemical properties. What is an element in chemistry? In chemistry, an element is a pure substance consisting of only one type of atom, distinguished by its … Read more

Biomolecules concept questions and answers

What are biomolecules? Biomolecules are any molecules that are produced by living organisms, including large macromolecules like proteins, nucleic acids, carbohydrates, and lipids, as well as small molecules like primary metabolites, secondary metabolites, and natural products. What is the primary function of proteins in the body? Proteins play a wide variety of roles in the … Read more

Corrosion concept questions and answers

What is corrosion in the context of chemistry? Corrosion refers to the destructive and spontaneous oxidation process of metals reacting with the environment, resulting in the formation of oxides, hydroxides, or salts. For example, iron corrodes to form iron(III) oxide or rust. Why is corrosion often considered an electrochemical process? Corrosion is considered an electrochemical … Read more
