Question

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

Answer 1

The Options are as follow,

                               (1) CaCl₂ (s)     (3) CH₃OH (l)

                               (2) C₂H₆ (g)      (4) Cal₂ (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.
