Here are the essential concepts you must grasp in order to answer the question correctly.
Electronegativity
Electronegativity is a measure of an atom's ability to attract and hold onto electrons. In organic chemistry, oxygen is highly electronegative, meaning it pulls electron density towards itself when bonded to other atoms. This property influences the distribution of electron density in molecules, affecting their reactivity and interactions.

Resonance Structures
Resonance structures are different ways of drawing a molecule that represent the same compound, showing the delocalization of electrons. In compounds with resonance, the electron density can be spread over multiple atoms, including oxygen. Understanding resonance helps predict where electron density is concentrated, which is crucial for determining the reactivity of the compound.

Inductive Effect
The inductive effect refers to the transmission of charge through a chain of atoms in a molecule due to the electronegativity of nearby atoms. Electron-withdrawing groups can decrease electron density on an oxygen atom, while electron-donating groups can increase it. This effect is important for analyzing how substituents influence the electron density on functional groups like alcohols or ethers.
