Question
Chapter 2, Problem 2.19P
Interpretation Introduction
(a)
Interpretation:
The melting points are to be matched with the given compounds.
Concept introduction:
Melting point is temperature above which it is changed from solid to liquid state. It is an important property for a compound as it is used to determine the purity of the compounds. In case of impurities, the analyzing compounds melting point will be low. The melting point of the branched hydrocarbons is less as compared to the straight chain hydrocarbons as the branching perturbs the packing in the crystal.
