**Solvolysis Reaction:**
Solvolysis is a type of reaction in which a chemical compound reacts with a solvent molecule to form new products. This reaction occurs due to the breaking of bonds within the compound and subsequent formation of new bonds with the solvent molecule.

**Expected Products:**
To determine the expected products of a solvolysis reaction, we need to consider the nature of the compound undergoing solvolysis and the solvent used in the reaction. The reaction can be classified into two types:

1. Nucleophilic Solvolysis:
In nucleophilic solvolysis, the solvent acts as a nucleophile and attacks the electrophilic center of the compound. The expected products depend on the nature of the substrate and the solvent.

- If the substrate is an alkyl halide (RX) and the solvent is water (H2O):
- The alkyl halide will undergo nucleophilic substitution, where the halogen atom is replaced by a hydroxyl group (OH-).
- The expected product will be an alcohol (ROH), with the halogen being replaced by a hydroxyl group.

- If the substrate is an ester (RCOOR') and the solvent is water (H2O):
- The ester will undergo nucleophilic acyl substitution, where the alcohol portion of the ester is replaced by a hydroxyl group (OH-).
- The expected product will be a carboxylic acid (RCOOH), with the alcohol portion of the ester being replaced by a hydroxyl group.

2. Elimination Solvolysis:
In elimination solvolysis, the solvent acts as a base and removes a proton from the compound to form an alkene.

- If the substrate is an alcohol (ROH) and the solvent is concentrated sulfuric acid (H2SO4):
- The alcohol will undergo dehydration, where a water molecule is eliminated from the compound.
- The expected product will be an alkene (R2C=CR2), with the elimination of a water molecule from the alcohol.

- If the substrate is an alkyl halide (RX) and the solvent is concentrated sulfuric acid (H2SO4):
- The alkyl halide will undergo elimination, where a halogen atom is eliminated along with a proton from the compound.
- The expected product will be an alkene (R2C=CR2), with the elimination of the halogen atom and a proton from the alkyl halide.

In summary, the expected products of a solvolysis reaction depend on the nature of the substrate and the solvent. Nucleophilic solvolysis results in the substitution of functional groups, while elimination solvolysis leads to the formation of alkenes.
