Consider the species CH 4 , NH 4 + and BH 4 - . Choose the correct option with respect to the there species:

Options

  1. AThey are isoelectronic and only two have tetrahedral structures
  2. BThey are isoelectronic and all have tetrahedral structures
  3. COnly two are isoelectronic and all have tetrahedral structures
  4. DOnly two are isoelectronic and only two have tetrahedral structures

Correct answer

B. They are isoelectronic and all have tetrahedral structures

Step-by-step solution

In   CH 4 ,   NH 4 + ,   BH 4 -   the number of electrons are 10 for each. Hence, all the three species given are isoelectronic, and the central atom shows sp 3 hybridization. Hence, they have tetrahedral structure.
