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
***You can only use each answer one time.
Explanation / Answer
amphoteric acid
Al2O3 is amphoteric oxide due to less size of cation.
Lewis acid
BF3 is lewis acid . it contains vacant p-orbital
semiconductor
Si is metalloid. it act as semiconductor
strong oxidicing agent
HNO3 is trong acid . so it act as strong oxidicing agent.
polar molecule violent the octet rule
:.N=O
