The three compounds have essentially the same molar mass (5860 g/mol), so we must look at differences in polarity to predict the strength of the intermolecular dipoledipole interactions and thus the boiling points of the compounds. The effect is most dramatic for water: if we extend the straight line connecting the points for H2Te and H2Se to the line for period 2, we obtain an estimated boiling point of 130C for water! Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. intermolecular forces. Consequently, N2O should have a higher boiling point. When one dipole molecule comes into contact with another dipole molecule, the positive pole of the one molecule will be attracted to the negative pole of the other, and the molecules will be held together in this way. How much heat is released for every 1.00 g sucrose oxidized? Why are dipole-induced dipole forces permanent? CaCO3(s) Which of the following properties indicates the presence of strong intermolecular forces in a liquid? Source: Hydrogen Bonding Intermolecular Force, YouTube(opens in new window) [youtu.be]. Argon and N2O have very similar molar masses (40 and 44 g/mol, respectively), but N2O is polar while Ar is not. Hydrogen bonding between O and H atom of different molecules. Or is it hard for it to become a dipole because it is a symmetrical molecule? So you might expect them to have near identical boiling points, but it turns out that CH3CH2OH 2. In the long straight chain, the molecules can lay on one another more efficiently and have more surface area with which to interact. H3C-CH3 H3C-CH2-I H3C-CH2-Br H3C-CH2-Cl H3C-CH2-F 3 Answers Ethyl-fluoride would be the most polar since there is the highest difference in electronegativities between the adjacent functional groups (ethyl and fluorine). This molecule has an H atom bonded to an O atom, so it will experience hydrogen bonding. Andrew Wang 1C Posts: 101 Joined: Thu Oct 01, 2020 5:11 am Been upvoted: 5 times.
