MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

Nanomaterials are classified based on the number of dimensions that are in the nanoscale range (1 to 100 nm). Zero-dimensional (0D) nanomaterials have all three dimensions in the nanoscale ( One-dimensional (1D) nanomaterials have two dimensions in the nanoscale and one dimension outside the nanoscale. Examples include nanotubes and nanowires. Two-dimensional (2D) nanomaterials have one dimension in the nanoscale and two dimensions outside the nanoscale. Examples include thin films and coatings. Since nanoshells are zero-dimensional nanomaterials, they have all three dimensions less than 100 nm.
