A solid A^(o+)B^(ɵ) has NaCl -type close-packed structure. If the anion has a radius of 250 pm, what should be the ideal radius for the cation? Can a cation C^(o+) having radius of 180 pm be slipped into the tetrahedral site of the crystal A^(o+)B^(ɵ) ? Give reason for your answer.

Which one has the highest acidity ? SO_(3) , P_(2) O_(5) , ZnO , Na_(2)O
