Since electrons are constantly moving, at any given time, one atom will be more electronegative than the other atom. 9 Which has a higher boiling point H2O or H2S? So I initially thought, since S has a higher electronegativity than Se, H2S would have the higher boiling point. In H2O and H2S , Oxygen and Sulphur are the central atoms respectively.Among Oxygen and Sulphur , Oxygen is more electronegative (tendency to gain electrons) and hence it can form more number of intermolecular H bonding with other water molecules than Sulphur in H2S. LDF is found in every bond because its the most basic form of molecular attraction. However, in the chemistry textbook version 6 p.484, H2Se is expected to be a stronger acid than H2S because H2Se has weaker bonds. 3 Does H2S have the highest boiling point? As for these conflicting explanations, stronger bonds make boiling point greater and conversely, pH higher (less acidic). H2Se has the higher boiling point because it has a larger mass and more electrons. only weak hydrogen bonds; therefore, its average "effective" Explain your reasoning a) H2S vs H2Se b . 4 When compared to H2S H2O has a higher boiling point because H2O contains stronger?

Amongst `H_2 O, H_2 S, H_2 Se` and `H_2 Te`, the one with the highest boiling point is: `H_2 O` because of hydrogen bonding, `H_2 Te` because of higher molecular weight, `H_2 S` because of hydrogen bonding, `H_2 Se` because of lower molecular weight. However, it is observed that the boiling point of H2O is highest among these hydrides. What is thought to influence the overproduction and pruning of synapses in the brain quizlet? 6 Which is more electronegative in H2O or H2S? So, less energy is required to break the hydrogen bonds in H2S. 5 Why does H2Se have a higher boiling point than H2S? Chemistry. Which of the following has lowest boiling point H2O H2S H2Se? This is because of the lower electronegativity of sulphur than oxygen.
