Introduction to Hydrocarbons: Organic Compounds Day 1
Describe the historical understanding of compounds in the early 19th century.
Chemist knew living things produced a variety of carbon compounds, labeled as “organic", but could not synthesize them in the lab.
What did Wohler achieve in the field of organic chemistry?
Wohler was the first to produce organic compounds in the lab, challenging the belief that organic compounds could only be produced by living organisms.
How does carbon exhibit its unique bonding capabilities in organic compounds?
Carbon forms long chains and ring compounds through strong covalent bonds with other carbon atoms, leading to an enormous variety of stable carbon compounds.
Define the term “organic compounds” in chemistry.
Organic compounds refer to all carbon-containing compounds, excluding carbon oxides, carbides, and carbonates, which are classified as inorganic compounds.
What type of bonds does carbon typically form in organic compounds?
Carbon nearly always forms covalent bonds in organic compounds, sharing its electrons and forming four bonds.
Describe the typical elements to which carbon atoms bond in organic compounds.
Carbon atoms in organic compounds are bonded to hydrogen atoms or other elements near carbon on the periodic table, as well as to other carbon atoms to form long chains.
Describe the unique features of carbon bonding in hydrocarbons.
Carbon bonds are strong, carbon compounds are low in reactivity, and carbon can form 4 single bonds.
What is a diamond in the context of hydrocarbons?
A diamond is a covalent network solid and an allotrope of carbon.
Define allotropes in relation to elements like carbon.
Allotropes are forms of an element that differ in either bonding or structure.
How are hydrocarbons defined in terms of their compositions?
Hydrocarbons are the simplest organic compounds consisting only of carbon and hydrogen elements.
Explain the purpose of a Molecular Formula in chemistry.
A Molecular Formula tells which atom and how many of each type of atom are present in the molecule.
Explain the purpose of a Lewis Dot Structure in chemistry.
A Lewis Dot Structure shows how valence electrons are arranged around atoms in a molecule.
Explain the purpose of a VSPER Model in chemistry.
A VSPER Model determines bond angle and molecular shape.
Explain the purpose of a Space Filling Model (SPDF) in chemistry.
A Space Filling Model (SPDF) shows how much space an atom (or molecule) occupies.
What are saturated hydrocarbons characterized by?
Saturated hydrocarbons contain only single bonds.
What distinguishes unsaturated hydrocarbons from saturated hydrocarbons?
Unsaturated hydrocarbons contain at least one double or triple bond.
Describe the process of fractional distillation in refining hydrocarbons.
Fractional distillation involves boiling petroleum and collecting each group of components as they condense at different temperatures.
How are heavier fractions of hydrocarbons converted to lighter fractions in the refining process?
Heavier fractions are converted to gasoline or other lighter fraction by a process called cracking.
Define Petroleum
Petroleum, crude oil, is a complex mixture containing more than a thousand different compounds. It is broken down into simpler components or fractions to become more useful.
Define the octane rating system in the context of gasoline refinement.
Gasoline is modified by adjusting its composition to improve performance, resulting in the octane rating system.
