Question

In nanomaterials production, according to Aufbau principle the self-assembly of complicated structures takes place in a hierarchical fashion in the following sequence:
(A) the linear chains are bundled to form two-dimensional monolayers
(B) single molecules join up to form linear chains
(C) a finite number of independent molecules
(D) the two-dimensional monolayers are stacked to form the final three-dimensional crystal
Choose the correct answer from the options given below:

• (A) - (B), (C) - (D)
• (A) - (C), (B) - (D)
• (B) - (A), (C) - (D)
• (C) - (B), (A) - (D)

Hint:

The Aufbau principle is crucial in understanding the formation of nanomaterials, as it defines the sequential steps in their self-assembly from simple molecules to complex three-dimensional structures.

Answer 1

The Correct Option is B

Step 1: Understanding the self-assembly process.
In the Aufbau principle of nanomaterials, the self-assembly process occurs in a structured sequence. First, individual molecules (C) come together to form linear chains (B).

Step 2: Bundling to form monolayers.
Next, these linear chains (B) are bundled to form two-dimensional monolayers (A), which then stack to form the final three-dimensional crystal (D).
Final Answer: \[ \boxed{(2) \, (A) - (C), (B) - (D)} \]
