Answer:
Hllw
Explanation:
▶▶ (SiF6 )2- IS known (SiCl6 )2- is not known. in SiCl6(2-) the chlorine atom
(SiF6 )2- IS known (SiCl6 )2- is not known. in SiCl6(2-) the chlorine atomis much larger than flourine which
(SiF6 )2- IS known (SiCl6 )2- is not known. in SiCl6(2-) the chlorine atomis much larger than flourine whichdoes not allow the six chlorines to surround the silicon due to repulsions between chlorine atoms. ... Hence , due to interelectron repulsions between chlorine atoms the compound SiCl6 (2-) is unstable and not known.
Answer:smaller size of F as compared to Cl
Explanation:due to smaller size of F as compared to Cl , six small F atoms can be easily accommodated around si atom while cl cannot since f are present in smaller 2p orbital and cl are present in larger 3p orbital therefore interaction of f lone pair electron with d orbitals of silicon are stronger in f as compared cl
diamond has three dimensional network structure involving strong c-c bond .these bonds are difficult to break and hence melting point of diamond is very high
because it does not release H+ions on its own it accepts OH- ion from the water molecule to complete its octet and in turn releasee H+ ion therefore it is a weak acid
due to absence of d qrbitals b at the maximum can accommodate 8 electrons or 4 pairs of electron but not BF36 Iin which the covalency of b is 6
