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 (1-100 nm). Zero-dimensional (0D) nanomaterials have all three dimensions in the nanoscale. Examples include nanoparticles, quantum dots, and fullerenes. One-dimensional (1D) nanomaterials have two dimensions in the nanoscale. Examples include nanotubes and nanowires. Two-dimensional (2D) nanomaterials have one dimension in the nanoscale. Examples include graphene and nanofilms. Since nanoparticles have all three dimensions in the nanoscale, they are classified as zero-dimensional. Answer: zero dimensional
