In which 1.0 gram sample are particles arranged in a rystal structure?

The Options are as follow,

(1) CaCl ₂ (s) (3) CH ₃ OH (l)

(2) C ₂ H ₆ (g) (4) Cal ₂ (aq)

Answer:

Option-1 is the correct answer.

Explanation:

As we know crystal formation is the property of solids. Therefore, in given options we are given with four different states of matter.

Option A, CaCl₂ is in a solid state, so it can exist in crystal form.

Option 2, C₂H₆ (Ethane) is in gas form, so it cannot form crystals.

Option 3, CH₃OH (Methanol) is present in liquid form, so it fails to form crystals.

Option 4, CaI₂, it is dissolved in water, Hence, it is in aqueous state, Therefore it also lacks crystal structure.
