Q. Consider the following statements regarding Graphene and Fullerene: 

1. Graphene is 2 dimensional , Fullerene is generally 3 dimensional
2. Graphene is SP2 allotrope of Carbon, while Fullerene is SP3 allotrope of Carbon
3. Graphene does not dissolve in petrol but fullerenes dissolve

Which among the above statements is / are correct?

Answer: 1 & 3 are correct
Notes: All three statements are correct regarding Graphene and Fullerene: 1. Graphene is 2-dimensional, Fullerene is generally 3-dimensional: Graphene consists of a single layer of carbon atoms arranged in a hexagonal lattice, making it effectively 2D. Fullerenes, such as C60, are spherical or tubular structures, thus 3D. 2. Graphene is SP2 allotrope of Carbon, while Fullerene is SP3 allotrope of Carbon: In graphene, each carbon atom forms three sigma bonds with neighboring atoms (SP2 hybridization), while in fullerenes, carbon atoms are bonded in a way that can be considered SP3 hybridized due to their tetrahedral geometry. 3. Graphene does not dissolve in petrol but fullerenes dissolve: Graphene is hydrophobic and does not dissolve in non-polar solvents like petrol, while fullerenes can dissolve in organic solvents due to their molecular structure. Thus, the correct answer is that all statements are accurate.
