Question

Consider the species CH , NH and BH . Choose the correct option with respect to the species. 4 4+ 4– 4 3 4+ 3 4– 3 4 4+ 4–

(A) They are isoelectronic and only two have tetrahedral structures.
(B) They are isoelectronic and all have tetrahedral structures.
(C) Only two are isoelectronic and all have tetrahedral structures.
(D) Only two are isoelectronic and only two have tetrahedral structures.

Correct answer: B) THEY ARE ISOELECTRONIC AND ALL HAVE TETRAHEDRAL STRUCTURES.. CH is sp hybridized and tetrahedral in shape with 10 electrons. NH is sp hybridized and tetrahedral in shape with 10 electrons. BH is sp hybridized and tetrahedral in shape with 10 electrons. Therefore, CH , NH and BH are isoelectronic, and three of them have tetrahedral structure.
