MHT CET 2024 Chemistry question

Not in JEE or NEET syllabus

Which among the following is an example of one dimensional nanostructure ?

(A)Nano rings
(B)Nano tubesCorrect
(C)Layers and coatings
(D)Quantum dots

Answer: (B)

Solution

Nanomaterials are classified by the number of dimensions that lie outside the nanometre range (1-100 nm). One-dimensional nanostructures have only one dimension (length) outside the nano range, i.e. they are long and thin: nanowires, nanorods and nanotubes. So nanotubes, option (B), is the example. Layers
