Which of the following pairs of compound is isoelectronic and isostructure ?

Options

A. `TeI_(2),XeF_(2)`
B. `IBr_(2),XeF_(2)`
C. `IF_(3),XeF_(2)`
D. `BeCl_(2), XeF_(2)`

Answer

b

Explanation

Iso electric species are those which have same no of electron
Iso structure species are those which have same type of hybridization and shape
`Ibr_(2) `and `XeF_(2)` are iso electronic `Bir_(2)`
`H = (1)/(2) (7 + 2 + 1) = 5 rArr sp^(2)d`
`2` bond pair `3` pair rArr linear shape `XeF_(2)`
`H = (1)/(2) (8 + 2 )= 5 rArr sp^(2)d`
`2` bond pair `3` pair rArr linear shape
