Question
Matching: Give one example from the main-group chemistry that illustrates each of the following descriptors:
______________ Covalent Network Solid A. Chlorine gas
______________ Disproportionation reaction B. silicon
______________Paramagnetic oxide C. nitric acid
______________Polar molecule that violates the octet rule D. nitrogen dioxide
______________Lewis acid E. nitrogen monoxide
_____________Amphoteric oxide F. diamond
_____________Semiconductor G. graphite, fullerene
_____________Strong oxidizing agent H. Boron triblouride
____________Allotropes I. water
____________Universal polar solvent J. Aluminum oxide
Explanation / Answer
Covalent Network Solid --> diamond will form networks of covalents bonds
Disproportionation reaction --> Nitrogen dioxide
Paramagnetic oxide --> Aluminium oxide
Polar molecule that violates the octet rule --> Boron trifluoride, BF3, B contians only 6 bonded species, insted of 8
Lewis acid --> Boron trifluoride, BF3, acts as an acid
Amphoteric oxide --> can act as a base/acid, this is Aluminum oxide
Semiconductor --> silicon is a metalloid, therefore capable of being semiconductor
Strong oxidizing agent --> Chlorine gas, which reacts readily with any species
Allotropes --> graphite, fullerene are good exmaples
Universal polar solvent --> water is polar, and it is widely used
