ChemistryEasy42×since 2002Q1942CsCl crystallises in body centred cubic lattice. If ‘a’ is its edge length then which of the following expressions is correct?ArCs++rCl−=32a{r_{C{s^ + }}} + {r_{C{l^ - }}} = {{\sqrt 3 } \over 2}arCs++rCl−=23aBrCs++rCl−=32a{r_{C{s^ + }}} + {r_{C{l^ - }}} = {3 \over 2}arCs++rCl−=23aCrCs++rCl−=3a{r_{C{s^ + }}} + {r_{C{l^ - }}} = \sqrt 3 arCs++rCl−=3aDrCs++rCl−=3a{r_{C{s^ + }}} + {r_{C{l^ - }}} = 3arCs++rCl−=3aCheck answerSkip
