Inorganic Chemistry Concepts:
Hydrides:
- Compounds containing hydrogen bonded to another element.
- Can be ionic (e.g., NaH), covalent (e.g., NH3), or metallic (e.g., LaH2).
- Tricky Questions: Classifying hydrides based on their properties, predicting their reactivity, and understanding the role of hydrogen bonding.
Halides:
- Compounds containing a halogen (F, Cl, Br, I) bonded to another element.
- Can be ionic (e.g., NaCl), covalent (e.g., HCl), or complex (e.g., [FeCl4]-).
- Tricky Questions: Understanding the trends in reactivity and boiling points of halides, predicting the formation of different halide anions, and analyzing the role of halides in organic chemistry.
Oxoacids:
- Acids containing oxygen, hydrogen, and another nonmetal.
- Examples: H2SO4 (sulfuric acid), HNO3 (nitric acid), H3PO4 (phosphoric acid).
- Tricky Questions: Determining the oxidation state of the central atom, understanding the acidity trends, and predicting the products of acid-base reactions.
Oxide Compounds:
- Compounds containing oxygen bonded to another element.
- Can be ionic (e.g., Na2O), covalent (e.g., CO2), or amphoteric (e.g., Al2O3).
- Tricky Questions: Analyzing the structure and bonding of oxides, explaining the different types of oxides (basic, acidic, amphoteric), and understanding their role in the environment.
Interhalogens:
- Compounds containing two different halogens.
- Examples: ClF, BrF3, IF5.
- Tricky Questions: Predicting the structures and bond angles of interhalogens, understanding the reactivity and stability trends, and explaining the role of interhalogens in various reactions.
Hydrides of Group 17:
- Also known as hydrogen halides (HF, HCl, HBr, HI).
- Highly polar covalent compounds with significant hydrogen bonding.
- Tricky Questions: Understanding the acidic strength of hydrogen halides, predicting the products of reactions with metals and bases, and explaining the role of hydrogen halides in organic chemistry.
