Match the solid in Column - I with its characteristic in Column - II.
`{:("COLUMN - I","COLUMN - II"),("(Solid)","(Characteristic)"),("A) NaCl","p) Body centred cubic"),("B) CsCl","q) Packing fraction"),("C) Na","r) Packing fraction "=(2pi)/(3)((r_(+)^(3)+r_(-)^(3)))/((r_(+)+r_(-))^(3))),("D) TiCl","s) Packing fraction "(sqrt3)/(2)pi((r_(+)^(3)+r_(-)^(3)))/((r_(+)+r_(-))^(3))):}`

Text Solution

Verified by Experts

The correct Answer is:
`A-r; mB-p,s; C-pq; D-ps`
For `NaCl =(4xx(4)/(3)pi(r^(+)-r^(-))^(3))/(2^(3)xx(r^(+)-r^(-))^(3))=(2)/(3)(pi(r^(+)-r^(-))^(3))/((r^(+)-r^(-))^(3))=(4)/(3)(pi(r^(+)-r^(-)))/(((2)/(3))^(3)(r^(+)+r^(-))^(3))=(sqrt3)/(2)(pi(r^(+)-r^(-))^(3))/((r^(+)-r^(-))^(3))`
`Na-"BCC, P.F = 0.68, "TiCl" BCC P.F"=(sqrt3pi)/(2)((r^(+)-r^(-))^(3))/((r^(+)-r^(-))^(3))`
