The Correct Option is A
Approach Solution - 1
To determine the products of the given reaction, we need to consider the mechanism of the reaction between an ether and hydrogen iodide (HI). This reaction involves the cleavage of the C-O bond in the ether.
- The ether in the reaction is a cyclic structure with an isopropyl group attached to an oxygen atom.
- When HI is added to this ether, the iodine (I-) ion can attack the more sterically hindered carbon of the ether, leading to the formation of an alcohol and an alkyl iodide.
- In this reaction, the more hindered side is the tertiary butyl group. The iodine ion will attack here, leading to the cleavage of the C-O bond.
- This will produce isopropanol as the alcohol and tertiary butyl iodide as the alkyl iodide.
Therefore, the products of the reaction are isopropanol and tertiary butyl iodide.
Thus, the correct answer is the image showing isopropanol and tertiary butyl iodide.
Approach Solution -2
The given reaction involves the cleavage of the ether bond using \( \text{HI} \). The major products are formed through the nucleophilic substitution of \( \text{HI} \) on the ether linkage. The reaction mechanism proceeds as follows:
Protonation of the ether oxygen atom by \( \text{HI} \), resulting in the formation of an oxonium ion intermediate.
Cleavage of the \( \text{C–O} \) bond forms cyclohexanol and a tertiary carbocation (\((\text{CH}_3)_3\text{C}^+\)).
The tertiary carbocation rapidly reacts with \( \text{I}^- \) to form \((\text{CH}_3)_3\text{C–I}\) as the final product.

Chemical Reactions go with the breaking and bonding of covalent bonds which involve of exchange of electrons. The functional groups of Organic compounds play a consequential role in the process. Based on the above theory, reactions can be classified into five main groups:
Rearrangement Reactions are the type of reactions in which products get formed simply by the rearrangement of atoms and electrons in the reactant molecules.

||
NH4CNO → NH2 –C – NH2
Substitution Reactions are the reactions in which an atom or group of atoms is replaced by some other atom or group of atoms without any change in the structure of the remaining part of the molecule.
CH3Br + KOH (aqueous) → CH3OH + KBr
Addition Reactions are the reactions in which products get formed by the addition of some reagent to an unsaturated compound.
CH2 = CH2 + HCl → CH5Cl
- Electrophilic Addition Reactions
- Nucleophilic Addition Reactions
- Free Radical Addition Reactions
Elimination Reactions are the reactions in which the products get formed by the loss of simple molecules like HX from the reactant molecules.
C2H5OH → C2H4

- EN2 (Nucleophilic Elimination Bimolecular)
A polymerization Reaction is the union of two or more molecules of a substance that form a single molecule with higher molecular weight.
