Question:
Which of the following nano structures includes nanotubes as an example?
Which of the following nano structures includes nanotubes as an example?
Show Hint
A nanotube is thin in two directions and long in one.
Updated On: Oct 1, 2026
- Zero dimensional
- One dimensional
- Two dimensional
- Three dimensional
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Nanomaterials are grouped by how many of their dimensions lie outside the nanometre range (more than 100 nm). Zero dimensional means all three dimensions are in the nano range. One dimensional means two are nano and one is large. Two dimensional means one is nano and two are large.
Step 2: Examples:
Nanoparticles and quantum dots are zero dimensional. Nanotubes, nanowires and nanorods are one dimensional, because the diameter is nano but the length is large. Thin films and graphene sheets are two dimensional. Bulk crystals are three dimensional.
Step 3: Conclusion:
A nanotube has a nano-sized diameter and a long length, so it is one dimensional. The answer is option (B).
Final Answer:
Nanotubes are one dimensional nanostructures. \[ \boxed{B:\ \text{One dimensional}} \]
