Arrange the following in order of increasing boiling point. Bond dissociation energy usually decreases on moving down a group as the atomic size increases. Increasing molar mass generally means higher boiling points. Largest dipole moment to Smallest dipole moment. HClO, HClO 2, HClO 3, HClO 4 or H 2O, H 2S, H 2Se, H 2Te! ... question. HI H2Te H2O AsH3 . This is due to the small atomic size of fluorine. Solution: Option (i) and (iv) are ... H2O has higher bond angle than H2S because as we move from oxygen to sulphur the size of the central atom increases and electronegativity decreases due to which bond pair goes away from the central â¦ â¦ ClCH2CH2COOH BrCH2CH2COOH ICH2CH2COOH FCH2CH2COOH (A portion of the periodic table is shown on the other side) A. H2O < H2S < H2Se < H2Te B. H2Te < H2Se < H2S < H2O C. H2O < H2Te < H2Se < H2S D. H2S < H2Se < H2Te < H2O E. Don't know Anonymous. H2S, H2Se, ... Like look at the size of S and of Se and compare H2S and H2Se for water it is a different story since it forms hydrogen bonds. So, they have minimum bond angles group Water has the highest boiling point, as the hydrogen bonds between the molecules need more energy to break than the hdyrogen bonds in H2S, and H2Se, as Oxygen is much more electronegative than Sulphur of Selenium, so it makes the molecules more polar. As the number of oxygens increases, more electron density is drawn away from the OâH bond and weakens it. Solved: 1. order of oxidising power. Make certain each sentence is complete before submitting your answer. From what I understand, acidity increases because atomic radius increases down the group and bonds get bigger I suppose so â¦ I will try to give u a most appropriate and short answer that u can understand easily See h20 has 104.5 degrees bond angle , h2s has 92degrees , h2se has 91degrees and h2te has 90degrees bond angles Draw diagrams of these u will find all of them have tetrahedral shape with 2 lone pairs , assume that no â¦ a)dipole-dipole forces.
