Question

The molecules having the same hybridisation, shape and number of lone pairs of electrons are

(a) SeF₄, XeO₂F₂

(b) SF₄, XeF₂

(c) XeOF₄, TeF₄

(d) SeCl₄,XeF₄

Answer 1

Correct option  (a) SeF₄, XeO₂F₂

Explanation:

SeF₄ and XeO₂F₂, both are sp³ d hybridised, trigonal bipyramidal and see-saw shaped with one lone pair of electrons each. 

SF₄ has one lone pair, XeF₂ has 3 lone pairs. XeOF₄ is square pyramidal with 1 lone pair, TeF₄ is see-saw shaped with 1 lone pair, SeCl₄ has see-saw shape with 1 lone pair, XeF₄ has square planar shape with 2 lone pairs.
