If the radius of Br ion is 0.182 nm, the radius of biggest cation that can fit into its tetrahedral voids?

A

0.414 pm

B

0.0753 nm

C

0.091 nm

D

0.225 pm

Text Solution

Verified by Experts

The correct Answer is:
B
For tetrahedral void, `r_(+)/r_(-)=0.225-0.414`
`r_(+)=0.414xxr_(-)=0.414xx0.182nm=0.0753nm`.
`therefore` Cations of radius 0.0753 nm (maximum) can fir into each tetrahedral void.

The r_(+)//r_(-) ratio of ZnS is 0.402. Pick the false statement out of the statements given below : ZnS is 4 : 4 coordination compound, ZnS does not crystallize in rock salt type lattice because r_(+)//r_(-) is too small to avoid overlapping of S^(2-) ions., Zn^(2+) ion is too small to fit precisely into the octahedral voids of S^(2-) ions. , Zn^(2+) ion is too large to fit into the octahedral voids of S^(2-) ions.
