Interações Intermoleculares e Ponto de Ebulição

Comparison of Boiling Points in Relation to Intermolecular Forces. In this class, we will understand how we can compare the boiling temperatures of chemical substances in relation to the type of interaction or intermolecular force they perform. Two criteria are sufficient to determine the increasing order of boiling points of substances: size and the number of hydrogen bonds. 1) Solved FUVEST question (6:30) The following graph indicates the boiling temperature of bromoalkanes (CnH2n+1Br) for different carbon chain sizes. Considering the periodic properties of halogens, the alternative that adequately describes the behavior expressed in the graph of boiling temperatures versus carbon chain length for CnH2n+1F () and CnH2n+1I (•) is Note and adopt: B.P. = boiling point 2) FUVEST Question (13:46) In the production of biodiesel, glycerol is formed as a byproduct. The use of glycerol has been studied, aiming at obtaining other substances. 1,3-propanediol, used in the synthesis of certain polymers, is one of these substances that can be obtained from glycerol. The following diagram illustrates the process of obtaining 1,3-propanediol. 🔔 SUBSCRIBE TO THE CHANNEL 👍 Did you like the video? Leave your LIKE!
