11 Questions
What is the electronic configuration of carbon?
2, 4
Why can't carbon form an ionic bond?
It would be difficult for the nucleus with six protons to hold on to ten electrons.
Define covalent bond.
The bond formed by mutual sharing of electron pairs between two atoms in a molecule.
What does the electron dot structure represent in molecules?
The shared pairs of electrons and octet rule.
How many pairs of electrons are shared in a triple covalent bond?
Three
What is the phenomenon in which an element exists in two or more different physical states with similar chemical properties?
Allotropy
Name the three main allotropes of Carbon and briefly describe one unique property of each.
Diamond (hardness and insulator), Graphite (good conductor of electricity and lubricant), Buckminster Fullerene (spherical molecules)
What physical properties of organic compounds lead to their low boiling and melting points?
Weak inter-molecular force of attraction
Why are most carbon compounds poor conductors of electricity?
Absence of free electrons and free ions
What property of carbon allows it to form long straight, branched, and ring structures?
Catenation
Explain the versatile nature of carbon in terms of catenation and tetravalent nature.
Carbon's ability to form long chains and rings through covalent bonds (catenation) and its tendency to form four bonds due to having four valence electrons (tetravalent nature).
Learn about the covalent bond in carbon, electron dot structure, physical properties of organic compounds, and allotropes of carbon. Explore how carbon requires 4 electrons to achieve an inert gas electronic configuration and why it cannot form an ionic bond.
