10 Questions
Why are most carbon compounds poor conductors of electricity?
They do not give rise to any ions
How many valence electrons does carbon have?
4
How do elements forming ionic compounds achieve noble gas configuration?
By gaining or losing electrons from the outermost shell
What can be concluded about the bonding in carbon compounds?
It does not give rise to any ions
What is the atomic number of carbon?
6
Explain the property of catenation in carbon compounds and how it allows carbon to form a large number of compounds.
Catenation is the unique ability of carbon to form bonds with other atoms of carbon, giving rise to large molecules. This property allows carbon to form long chains of carbon, branched chains of carbon, or even carbon atoms arranged in rings, as well as the ability to form single, double, or triple bonds between carbon atoms. Compounds linked by only single bonds between the carbon atoms are called saturated compounds, while those with double or triple bonds are called unsaturated compounds. No other element exhibits the property of catenation to the extent seen in carbon compounds.
What is the estimated number of carbon compounds whose formulae are known to chemists, and how does it compare to compounds formed by all the other elements put together?
The estimated number of carbon compounds whose formulae are known to chemists is in the millions, outnumbering by a large margin the compounds formed by all the other elements put together.
Why does carbon have the unique ability to form a large number of compounds?
The nature of the covalent bond enables carbon to form a large number of compounds. This is attributed to carbon's property of catenation, where it can form long chains, branched chains, or rings of carbon atoms, as well as the ability to form single, double, or triple bonds between carbon atoms.
What are saturated and unsaturated compounds of carbon, and how do they differ?
Compounds of carbon linked by only single bonds between the carbon atoms are called saturated compounds, while those with double or triple bonds between the carbon atoms are called unsaturated compounds. Saturated compounds have no double or triple bonds, while unsaturated compounds contain double or triple bonds, making them capable of further reactions.
How does the property of catenation in carbon compounds compare to other elements, particularly silicon?
No other element exhibits the property of catenation to the extent seen in carbon compounds. Silicon forms compounds with hydrogen which have chains of up to seven or eight atoms, but these compounds are very reactive, and do not show the extensive catenation observed in carbon compounds.
