Question

During hydrochloric acid asshown in the reaction below. lab, you react an aqueous solution of benzoate ion with aqueous (6) 1. Use electron pushing arrows and diagram the reaction, drawing the structures ofthe products. Show all lone pair electrons. (1202 You take melting point ofthe crude product from above, using a 2.0 heating ramp, and find that it starts melting at 17.3 Cand is completely melted at 123.1 °C. After recrystallizing the crude product, you take a second melting point and find that it starts melting at and is completely melted at 122.1 ec. The literature value ofmelting point for the product is 122.2 eC. Analyze and discuss the data. witu a wider melting range An tha first awahsis, I would der if ma was not eal smaller anal s acter neeny hei zation data shu seems to te witwu. t i ne value.

Explanation / Answer

Discussion:
Unless you have prior knowledge of the expected melting point, it is advisable to have extra samples prepared ahead time. Run the first sample at a high rate of heating to get an approximate melting point range.Then repeat the procedure but slow down the rate of heating as you approach the expected melting point.

In he given analysis also first run was used to estimar=te the expected range of melting point and then second time it is carefuuly observed to reach to approximately same melting point.
