    Carbon’s unique catenation ability arises from its small atomic size and the strength of the carbon-carbon bond. Carbon’s small size allows its nucleus to hold shared electrons strongly, promoting the formation of stable covalent bonds. With a valency of four, carbon can form up to four bonds, creating diverse and stable compounds with various elements. This versatility enables the creation of long chains, branched structures, or rings in carbon compounds. The strength of carbon bonds, coupled with its tetravalency, distinguishes carbon’s extensive catenation and contributes to the vast diversity and stability observed in organic compounds.

    Elements that replace hydrogen in a hydrocarbon chain are termed heteroatoms. Heteroatoms, including halogens, oxygen, nitrogen, and sulfur, introduce functional groups into the compound, altering its chemical properties. These heteroatoms can participate in various chemical reactions, influencing reactivity, polarity, and intermolecular forces. For instance, the presence of oxygen in functional groups like hydroxyl (-OH) imparts polarity and the potential for hydrogen bonding. Nitrogen in amino groups (-NH₂) contributes basic properties. Heteroatoms enhance the diversity and specificity of organic compounds, playing a crucial role in the design and function of molecules in biological systems and synthetic materials.

    Functional groups are specific arrangements of atoms within a molecule that determine its chemical reactivity and properties. These groups are identified by their free valency, denoted by a single line, indicating the attachment point to the carbon chain. Functional groups play a pivotal role in determining the properties of carbon compounds, regardless of the carbon chain’s length. They confer specific chemical behaviors, reactivity patterns, and physical characteristics to the compounds. The diversity of functional groups allows for a wide range of organic molecules with distinct functionalities, influencing the roles of these compounds in biological processes, materials science, and various industrial applications.

    The copying of DNA during cell division is not absolutely accurate due to the potential for errors in DNA replication. Although cellular mechanisms, like proofreading enzymes, exist to maintain fidelity, occasional mistakes occur. Factors such as environmental damage, replication stress, or errors in the enzyme activity can lead to mutations. While organisms possess repair mechanisms to correct some mistakes, not all errors are identified and rectified. These mutations contribute to genetic diversity, enabling evolutionary processes. The imperfect accuracy in DNA replication is a trade-off between maintaining stability and allowing for the genetic variations essential for adaptation and survival in changing environments.
