Answer:
Crystallization of tetrafloroethane C₂F₄ is easier than styrene C₈H₈ .
Explanation:
Crystallization -
crystallization is a process in which atoms are restructured in the form of crystals , some of the ways by which crystals form are melting , precipitating from a solution.
we need to consider the melting point of the given compounds ,
the melting point of styrene C₈H₈ is -30 °C
whereas the melting point of tetrafloroethane C₂F₄ is -140 °C ( 130.7 K ) since the melting point of C₂F₄ is less than C₈H₈ so it is easy to melt C₂F₄.
Hence it is easier to crystallize C₂F₄ .
