The selenide, in contrast, forms In binary acids such as H2S and H2Se, the HSe bonds is longer than the HS bonds as Se is larger than S. The HSe bond is therefore weaker than the HS bond and H2Se is thus a stronger acid than H2S. So the actual trend here is H2S H2S < H2Se < H2Te < H2O Thi O This is the correct boiling point order. LDF is found in every bond because its the most basic form of molecular attraction. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet.
