Among the following, the pair in which the two species are not isostructural is
IO3- and XeO3
BH4- and NH4+
PF6- and SF
SiF4 and SF4
The Correct Option is D
Solution and Explanation
SiF4 (silicon tetrafluoride) and SF4 (sulfur tetrafluoride) have different molecular geometries and are not isostructural. SiF4 has a tetrahedral geometry with all bond angles at 109.5 degrees, while SF4 has a see-saw or distorted tetrahedral geometry with bond angles of approximately 101.6 degrees. So, the correct option is (D): SiF4 and SF4

- Given below are two statements :
Statement I : The boiling point of three isomeric pentanes follows the order
n-pentane > isopentane > neopentane
Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point.

Introduction to Organic Chemistry
Organic chemistry is the branch of chemistry that involves the scientific study of organic compounds. Organic chemistry primarily deals with the structure and chemical composition of organic compounds, the physical and chemical properties of organic compounds, and the chemical reactions undergone by these compounds.
Reaction Intermediates in Organic Chemistry:
Intermediates can be understood as the first product of a consecutive reaction. For example, in a chemical reaction, if A→B and B→C, then, B can be said to be the intermediate for reaction A→C. The reactions in organic chemistry occur via the formation of these intermediates.
Reagents in Organic Chemistry:
Reagents are the chemicals that we add to bring about a specific change to an organic molecule. Any general reaction in organic chemistry can be written as:
Substrate + Reagent → Product
Where the substrate is an organic molecule to which we add the reagent. Based on the ability to either donate or abstract electrons, the reagents can be classified as:
- Electrophiles
- Nucleophiles
