Chemistry Question on Alcohols, Phenols and Ethers
In which of the following sets, all the given species are isostructural?
A
CO2, NO2, ClO2, SiO2
B
PCl3, Al Cl3, BCl3, SbCl3
C
BF3, NF3, PF3, Al F3
D
BF-4 ,CCl4 ,NH+4 , PCl+4
Answer
BF-4 ,CCl4 ,NH+4 , PCl+4
Explanation
Solution
Isostructural species are the molecules that have the same shape and also the same connectivity. In the question, BF4- ,CCl4 ,NH4+ , PCl4+ are isostructural because they have tetrahedral structure. The atoms occupy one of the vertices of the tetrahedron around the central atom.
