MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

Nanomaterials are classified based on the number of dimensions that are not confined to the nanoscale range ( Zero-dimensional (0D) nanomaterials have all three dimensions in the nanoscale range (less than 100 nm). Examples include quantum dots, nanoparticles, and fullerenes. One-dimensional (1D) nanomaterials have two dimensions in the nanoscale and one macroscopic dimension. Examples include nanotubes, nanowires, and nanofibers. Two-dimensional (2D) nanomaterials have one dimension in the nanoscale and two macroscopic dimensions. Examples include thin films, graphene, and coatings. Therefore, quantum dots are the nanomaterials having all three dimensions less than 100 nm. Answer: Quantum dots
