Question: Examine about theOrganic Chemistry for Molecular Mass. Answer: The breaking point of Hexanal is 126.9 oC while the breaking point of 1-heptanol is 178.5 0C (Haynes, 2014). 1-heptanol has a higher breaking point than hexanal. The distinction in the breaking points can be clarified as far as the atomic structures of the two mixes and the idea of the intermolecular powers of fascination between the particles. The sub-atomic recipe of Hexanal is C6H12O and its sub-atomic mass is 100.16 g/mol (Haynes, 2014). The sub-atomic recipe of 1-heptanol is C7H16O and its sub-atomic mass is 116.20 g/mol. The structures are as demonstrated as follows. In 1-Heptanol, the oxygen molecule is legitimately clung to a hydrogen particle. Since oxygen is profoundly electronegative, the O-H bond is exceptionally polar; with the oxygen end getting a halfway negative charge and the H end being somewhat positive. The oxygen particle of one atom pulls in the Hydrogen atom of a neighboring atom prompting arrangement of Hydrogen holding between the atoms. Hydrogen bonds are the most grounded between sub-atomic powers and require a great deal of vitality to defeat consequently the bizarrely high breaking point of 1-heptanol. In Hexanal, the Oxygen iota isn't reinforced straightforwardly to a hydrogen particle thus no hydrogen holding between atoms. The oxygen molecule frames a twofold bond with carbon. Since O is more electronegative than C, the O=C bond is profoundly polar, with the Oxygen end procuring a halfway negative charge and the Carbon end an incomplete positive charge along these lines, shaping a perpetual dipole. The dipole of one atom draws in the oppositely charged finish of another particle prompting arrangement of dipole-dipole attractions between particles. The dipole-dipole powers are moderately solid, giving hexanal a fundamentally higher breaking point contrasted with other natural particles of the tantamount mass. Be that as it may, these powers are not as solid as hydrogen bonds and therefore clarify why the breaking point of hexanal is lower than that of 1-heptanol. References Haynes,W.M. (2014).
