Correct option is A
The correct answer is (a) Statement II is correct, and Statement I is incorrect.
Explanation:
- Most carbon compounds are not good conductors of electricity.
- The force of attraction between the molecules of many carbon compounds (especially organic compounds) is generally not very strong, particularly for hydrocarbons and other non-polar molecules.
- These compounds tend to have van der Waals forces (also called London dispersion forces), which are relatively weak compared to other types of intermolecular forces like hydrogen bonds or ionic bonds.
Here's why:
Non-polar nature: Many organic compounds, such as alkanes, alkenes, and alkynes, are non-polar because the electrons are shared more or less equally between the atoms, especially when the atoms involved have similar electronegativities (like in C-H bonds). Since there is no significant charge separation, the intermolecular forces between the molecules are weak.
Weak van der Waals forces: These are the result of temporary fluctuations in electron distribution around the molecules, creating instantaneous dipoles. While these forces allow the molecules to be attracted to each other, they are much weaker than other intermolecular forces like hydrogen bonding, which is much stronger in compounds like water or alcohols.
