Question

Which of the following statements is correct? The boiling point of H_2O is significantly higher than H2S greater dispersion forces. The boiling point of H_2S is significantly higher than H2S greater dispersion forces. The boiling point of H_2O is significantly higher than H2s presence of H-bonding. The boiling point of H_2S is significantly higher than The best explanation for the fact that diamond is electronic structures are made up of atoms that are intrinsically hard because of tl are formed under extreme conditions of temperature and pressure neighboring atoms are giant molecules in which each atom forms strong covalent tend, with all of its neighboring contains orbitals or bands of delocalized electrons that belong not to single atoms but to each crystal as a whole

Explanation / Answer

Answer – 27) We are given boiling point relationship between H2O and H2S.

We know the H2O has hydrogen bonding and due to hydrogen bonding there is boiling point for H2O is significantly high than H2S. In the H2S there is hydrogen bonding and we know hydrogen bonding is stronger than dispersion forces. So statement C is correct.

28) We know the diamond has the giant molecular structure and all carbons are attached to each other very strong covalent bonds, so due to that diamond is extremely hard crystals.

So statement c is the best explanation for the fact that diamond is extremely hard crystals
