Question

The solid state structure of HF is 

 

• A. (A)
• B. (B)
• C. (C)
• D. (D)

Hint:

In solid HF, the molecules form a chain-like structure with hydrogen bonds between the hydrogen and fluorine atoms.

Answer 1

The Correct Option is B

Step 1: Understanding the structure of HF in solid state.
In the solid state, hydrogen fluoride (HF) forms hydrogen bonds between adjacent molecules. The molecules are aligned such that each HF molecule is bonded to several others by hydrogen bonds, forming chains. The structure is essentially a linear chain where hydrogen atoms bond to fluorine atoms, and each fluorine atom also forms hydrogen bonds with other hydrogen atoms.

Step 2: Analyzing the options.
(A) Correct: This structure accurately represents the hydrogen bonding arrangement in the solid state. The fluoride ions form hydrogen bonds with the hydrogen atoms of neighboring molecules.
(B), (C), (D): Incorrect, as they do not represent the correct bonding pattern in the solid state.

Step 3: Conclusion.
The correct answer is (A).
