In which of the following sets, all the given species are isostructural?
CO2, NO2, ClO2, SiO2
PCl3, Al Cl3, BCl3, SbCl3
BF3, NF3, PF3, Al F3
BF-4 ,CCl4 ,NH+4 , PCl+4
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.
The order of acidity of the following compounds is:
(i) o-Nitrophenol
(ii) Phenol
(iii) o-Cresol
(iv) Ethanol
