Chemical Bonding - Result Question 53
####28. Among the following species, identify the isostructural pairs.
$$ NF _3, NO _3^{-}, BF _3, H _3 O^{+}, N _3 H $$
$(1996,1 M)$
(a) $\left[NF _3, NO _3^{-}\right]$and $\left[BF _3, H _3 O^{+}\right]$
(b) $\left[NF _3, N _3 H\right]$ and $\left[NO _3^{-}, BF _3\right]$
(c) $\left[NF _3, H _3 O^{+}\right]$and $\left[NO _3^{-}, BF _3\right]$
(d) $\left[NF _3, H _3 O^{+}\right]$and $\left[N _3 H, BF _3\right]$
Show Answer
Solution:
Therefore, $NF _3, H _3 O^{+}$and $BF _3, NO _3^{-}$pairs have same shape.
