Consider the species CH4, NH4+ and BH4-. Choose the correct option with respect to the there species:
 
  1. They are isoelectronic and only two have tetrahedral structures
     
  2. They are isoelectronic and all have tetrahedral structures
     
  3. Only two are isoelectronic and all have tetrahedral structures
     
  4. Only two are isoelectronic and only two have tetrahedral structures

Solution

In CH4, NH4+, BH4- the number of electrons are 10 for each.

Hence, all the three species given are isoelectronic, and the central atom shows sp3 hybridization. Hence, they have tetrahedral structure.
