Statement I: Fluoroethanal has two stereomeric enols in which cis enol predominates at equilibrium.
Statement II: Intramolecular H-bonding increases the stability of a stereomer.
Explanation:
To understand the relationship between the two statements, let's break them down and analyze each one separately.
Statement I: Fluoroethanal has two stereomeric enols in which cis enol predominates at equilibrium.
The statement is referring to the isomerism of fluoroethanal, specifically the enol form. Enols are tautomers of carbonyl compounds and exist in equilibrium with the keto form. In the case of fluoroethanal, it can exist in two stereoisomeric enol forms: cis and trans.
The term "cis" refers to the arrangement where the hydrogen atom and the hydroxyl group are on the same side of the double bond. The term "trans" refers to the arrangement where the hydrogen atom and the hydroxyl group are on opposite sides of the double bond.
According to the statement, at equilibrium, the cis enol predominates. This means that the cis form is more stable or energetically favored compared to the trans form.
Statement II: Intramolecular H-bonding increases the stability of a stereomer.
This statement discusses the role of intramolecular hydrogen bonding in increasing the stability of a stereoisomer. Intramolecular hydrogen bonding occurs when a hydrogen atom forms a bond with an electronegative atom within the same molecule.
In the context of stereoisomerism, intramolecular hydrogen bonding can affect the stability of different stereoisomers. It can influence the arrangement of functional groups or substituents around a double bond, leading to different conformations or spatial arrangements.
By forming intramolecular hydrogen bonds, the stability of a stereoisomer can be increased due to the favorable interactions between the hydrogen atom and the electronegative atom involved in the bonding.
Explanation of the relationship between the two statements:
The two statements are related because the predominance of the cis enol in fluoroethanal at equilibrium can be attributed to the intramolecular hydrogen bonding present in the molecule.
Conclusion:
Both Statement I and Statement II are correct. Statement II provides the correct explanation of Statement I. The intramolecular hydrogen bonding in fluoroethanal increases the stability of the cis enol form, thereby making it predominate at equilibrium.
Statement II: Intramolecular H-bonding increases the stability of a stereomer.
