The correct answer is C. 1 and 2.
Benzene and toluene are both aromatic organic compounds. Aromatic compounds are a class of organic compounds that are characterized by a ring structure of carbon atoms. The ring structure is what gives aromatic compounds their unique properties.
In benzene, the six carbon atoms are arranged in a regular hexagon. The carbon atoms are all sp2 hybridized, which means that they have three sp2 orbitals that are used to form sigma bonds with the other carbon atoms and one p orbital that is perpendicular to the plane of the ring. The p orbitals of the carbon atoms overlap to form a pi bond that circles the ring.
Toluene is a derivative of benzene. It is formed when a methyl group (CH3) is added to the benzene ring. The methyl group is attached to one of the carbon atoms in the ring.
Both benzene and toluene are flammable and toxic. They are also used in a variety of products, including gasoline, plastics, and solvents.
Here is a brief explanation of each option:
- Option A: Only 1 is correct. This option is incorrect because statement 2 is also correct.
- Option B: Only 2 is correct. This option is incorrect because statement 1 is also correct.
- Option C: 1 and 2 are correct. This option is correct because both statements 1 and 2 are correct.
- Option D: None of these. This option is incorrect because both statements 1 and 2 are correct.
