Assertion.If the length of the unit cell of LiCl having NaCl structure is 5.14 Å, the ionic radius of Cl^- ion 1.82 Å Reason. Anion-anion contact is retained in LiCl structure because anions constitute the lattice.

Assertion.If the length of the unit cell of LiCl having NaCl structure

1.	Assertion.If the length of the unit cell of LiCl having NaCl structure is 5.14 Å, the ionic radius of Cl^- ion 1.82 Å Reason. Anion-anion contact is retained in LiCl structure because anions constitute the lattice.
Answer» If both assertion and reason are true, and reason is the true explanation of the assertion. If both assertion and reason are true, but reason is not the true explanation of the assertion. If assertion is true , but reason is false If both assertion and reason are false. SOLUTION :If anion-anion contact is retained, then is shown in the adjoininig Interionic distance of LiCl =`a/2` `="5.14 Å"/2`=2.57 Å `BC=sqrt(AB^2+AC^2)=sqrt((2.57)^2+(2.57)^2)` =3.63 Å Radius of `CL^-` ion =`1/2BC =1/2xx3.63`=1.81 Å Hence , R is the CORRECT explanation of A.
