What is the difference between metallic and non metallic oxides?
2 answers:
Answer:
Metals react with oxygen to form metallic oxide while Nonmetals react with oxygen to form non-metallic oxide. metallic oxides are basic in nature while Nonmetallic oxides are acidic in nature.
Metal oxides are compounds composed of metal ions and oxide ions. Nonmetal oxides are compounds composed of nonmetal atoms and oxygen atoms. The main difference between metal oxides and non-metal oxides is that metal oxides are basic compounds whereas nonmetal oxides are acidic compounds.
METALS:
Metals usually do not combine with hydrogen. Only a few reactive metals combine with hydrogen to form ionic metal hydrides.

NON-METALS:
Non-metals react with hydrogen to form stable, covalent hydrides.

Answer: Option (B) is the correct answer.
Explanation:
A molecules that will have more number of hydrogen bonding will has highest boiling point because to break the hydrogen bonds high heat needs to be provided.
So, in the molecule there is presence of two alcoholic groups. Hence, it will have strongest hydrogen bonding as compared to the rest of molecules.
In the molecule there will be hydrogen bonding and dipole-dipole interactions. Hence, it boiling point will be slightly less than
.
In the molecule , there will be only hydrogen bonding. Hence, its boiling point is less than
.
In the molecule , there is no hydrogen bonding but there will be only dipole-dipole interactions. Hence, its boiling point will be the least.
Therefore, we can conclude that increasing order of boiling point will be as follows.
