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

The question pertains to the solid-state structure of hydrogen fluoride (HF). In the solid state, HF forms a zigzag structure due to hydrogen bonding.

Explanation:

• Hydrogen fluoride molecules are highly polar, and they form strong hydrogen bonds.
• In the solid state, these hydrogen bonds lead to the formation of a chain-like zigzag structure. This is because each hydrogen atom forms a hydrogen bond with a fluorine atom of an adjacent HF molecule.
• As a result, HF arranges itself in a non-linear pattern to maximize hydrogen bonding, which stabilizes the structure.

The correct representation of this zigzag structure corresponds to option (B).
