The radius of the

\mathrm{N}{\mathrm{a}^ + }

is 95 pm and that of

\mathrm{C}{\mathrm{l}^ - }

ion is 181 pm. Predict the co-ordination number of

\mathrm{N}{\mathrm{a}^ + }

View answer and explanation

Correct option: B

Option B (6) is correct because the radius ratio of Na+ to Cl- falls within the range that favors an octahedral coordination number.
