MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

Nanomaterials are classified based on the number of dimensions that lie in the nanoscale range (1 to 100 nm). Zero-dimensional (0D) nanomaterials have all three dimensions in the nanoscale. Examples include quantum dots and nanoparticles. One-dimensional (1D) nanomaterials have two dimensions in the nanoscale. Examples include nanowires and nanotubes. Two-dimensional (2D) nanomaterials have exactly one dimension in the nanoscale. Examples include thin films, graphene, and nanosheets. Three-dimensional (3D) nanomaterials have no dimensions in the nanoscale but possess nanoscale features. Since thin films have only one dimension (thickness) less than 100 nm, they are classified as 2D nanomaterials. Answer: Thin films
