Draw the structural formula for a linear sixcarbon hydrocarbon that contains only \(C-C\) single bonds. Show all \(\mathrm{H}\) and \(\mathrm{C}\) atoms.

Hydrocarbons are organic compounds composed exclusively of hydrogen and carbon atoms. They are the simplest form of organic molecules and serve as the foundational building blocks for more complex organic compounds. There are different types of hydrocarbons, classified based on their structural features.

The simplest hydrocarbons are alkanes, which have only single bonds between carbon atoms and exhibit a saturated structure. This means that each carbon atom has formed the maximum number of bonds with hydrogen atoms, creating a stable molecule. Other types include alkenes and alkynes, with double and triple bonds respectively, and are considered unsaturated.

Significance in Chemistry

In terms of importance, hydrocarbons are not just fundamental in organic chemistry; they are also key components in various industries. Fuels like gasoline and diesel are refined from crude oil, which is mainly composed of hydrocarbons. The vast array of hydrocarbon derivatives are employed in manufacturing plastics, solvents, and countless other products that form the crux of modern life.

A molecular formula provides the exact number of each type of atom in a molecule, serving as a concise way to represent the composition of chemical compounds. In organic chemistry, the molecular formula is particularly useful for identifying different isomers. Isomers are compounds with the same molecular formula but different structural formulas, meaning that the atoms are connected in distinctive ways.

Decoding a Molecular Formula

In the provided exercise, the molecular formula for a six-carbon alkane is given as \(C_6H_{14}\). This indicates the molecule contains six carbon atoms and fourteen hydrogen atoms. The formula is derived from the general formula for alkanes, which is \(C_nH_{2n+2}\). By substituting the number of carbon atoms into this formula, we obtain the corresponding molecular formula for any straight-chain alkane. Understanding and using molecular formulas is essential in the synthesis and analysis of organic compounds.

Organic chemistry is the branch of chemistry that deals with the study of carbon-containing compounds and their reactions. It is a vast and complex field that includes the structures, synthesis, and dynamics of these compounds. Organic compounds are numerous and varied, with properties and applications that are vital in biological processes, industrial applications, and scientific research.With hydrocarbons as the simplest organic compounds, the field expands to include functional groups such as alcohols, ketones, and carboxylic acids, which greatly increase the diversity and capabilities of organic molecules.

Role in Life and Technology

Organic chemistry not only underpins all life on Earth with compounds like DNA and proteins being organic molecules, but it is also instrumental in developing new materials and medicines. Its principles are crucial for designing synthetic pathways, understanding molecular interactions, and catalysis, which allows chemists to create compounds with precision and tailored properties for specific uses.
