Which of the following statements are correct for carbon compounds?a)M...
Explanation:
The correct statements for carbon compounds are as follows:
B: Most carbon compounds are poor conductors of electricity.
- Carbon compounds are usually covalent compounds, which means they have shared electron pairs between atoms.
- Covalent compounds do not have free electrons that can move and carry an electric charge, so they are generally poor conductors of electricity.
C: Force of attraction between molecules of carbon compounds is not very strong.
- Carbon compounds are formed by carbon atoms bonding with other elements like hydrogen, oxygen, nitrogen, etc.
- These bonds are typically covalent bonds, which are formed by the sharing of electrons.
- Covalent bonds are relatively weaker compared to ionic or metallic bonds, which means the force of attraction between molecules of carbon compounds is not very strong.
Therefore, the correct statements for carbon compounds are B and C. Most carbon compounds are poor conductors of electricity, and the force of attraction between molecules of carbon compounds is not very strong.
Which of the following statements are correct for carbon compounds?a)M...
Statement a) Most carbon compounds are good conductors of electricity.
This statement is incorrect. Carbon compounds, in general, are poor conductors of electricity. Carbon itself is a non-metal and does not conduct electricity. However, there are a few exceptions such as graphite and graphene, which are forms of carbon that have a unique structure that allows them to conduct electricity.
Statement b) Most carbon compounds are poor conductors of electricity.
This statement is correct. Carbon compounds are typically poor conductors of electricity. This is because most carbon compounds have covalent bonds, which involve the sharing of electrons between atoms. Covalent compounds tend to have strong bonds, which restrict the movement of electrons, making them poor conductors of electricity.
Statement c) Force of attraction between molecules of carbon compounds is not very strong.
This statement is correct. The force of attraction between molecules of carbon compounds is generally not very strong. Carbon compounds, such as organic compounds, often have relatively weak intermolecular forces, such as Van der Waals forces or London dispersion forces. These forces are weaker compared to ionic or metallic bonds, resulting in lower boiling and melting points for carbon compounds.
Statement d) Force of attraction between molecules of carbon compounds is very strong.
This statement is incorrect. The force of attraction between molecules of carbon compounds is not very strong. As mentioned earlier, carbon compounds typically have weak intermolecular forces, making them relatively easy to break or separate. This is why many carbon compounds are volatile and have low boiling points.
In conclusion, carbon compounds are generally poor conductors of electricity, and the force of attraction between their molecules is not very strong. However, it is important to note that there are exceptions to these generalizations, such as graphite and graphene, which have unique properties due to their distinct structures.
