Assertion : Conductivity of silicon increases by doping it with group-15 elements.
Reason : Doping means introduction of small amount of impurities like P, As or Bi into the pure crystal.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Which of the following shows bond in silicone?
Si-C-Si-C-Si
Si-Si-Si-Si
-Si-O-Si-O-Si-
Si-C-Si-O-Si
Which of the following products are formed when SiCl4 vapour are passed over hot Mg ?
SiCl2 + MgCl2
Si + MgCl2
Mg2Si + MgCl2
MgSiCl6
Which of the following gas is linear ?
CO2
SO2
NO2
SO3
A.
CO2
In CO2 ,the bond length (C-O) is 1.15 ,hybridization of C in CO2 is sp .Thus it has a linear structure .
O=C=O O+=C-O- O--CO+ .
