NEET Chemistry The Solid State Questions Solved


A solid AB has the NaCl structure. If radius of cation A+ is 120 pm, calculate the maximum possible value of the radius of the anion B

(1) 240 pm

(2) 280 pm

(3) 270 pm

(4) 290 pm

(4) We know that for the NaCl structure

radius of cation/radius of anion = 0.414; rA+rB=0.414; rB=rA+0.414=1200.414=290pm
