What is the purpose of determining the melting point of organic substances?

The melting point is an important physical property of a compound. The melting point can be used to identify a substance and as an indication of its purity. The melting point of solid is defined as the temperature at which the solid exists in equilibrium with its liquid under an external pressure of one atmosphere.Click to see full answer. Then, what is the purpose of determining the melting point of solids?The melting point is a physical property of a solid and can be used to help identify a substance. In practice, a solid usually melts over a range of temperatures rather than at one specific temperature. For example, if an unknown solid melts at 102-106° C, the 4° range suggests that the sample is impure.Secondly, what are two reasons that organic chemists measure the melting points of solids? Organic compounds have low melting and boiling points, are volatile and slow reacting, covalent compounds. Unlike inorganic compounds, they react in vigorous conditions like high temperature, pressure, and in the presence of catalysts. Accordingly, what affects melting point of organic compounds? A strong attraction between molecules results in a higher melting point. In organic compounds, the presence of polarity, especially hydrogen bonding, usually leads to a higher melting point. The melting points of polar substances are higher than the melting points of nonpolar substances with similar sizes.Why is melting point important?The melting point is an important physical property of a compound. The melting point can be used to identify a substance and as an indication of its purity. The melting point of solid is defined as the temperature at which the solid exists in equilibrium with its liquid under an external pressure of one atmosphere.
