Simply put, HO=CH2CH2CH3 and HO-CH2CH2CH3. The second structure has a lone pair of electrons on the oxygen atom making the the neighbouring C partialy positive.

Resonance structure
Resonance structures refer to bonding in molecules or ions that cannot be correctly represented by a single Lewis structure. The Lewis dot structures show valence electrons.
The difference between the actual energy of the molecule and that of most stable resonating structure is known as Resonance Energy.
Resonance
yes
Resonance structure of butadiene explains H2C. This is known as carbon and hydrogen.
The actual structure
no
no
No, the structure of the compound shifts back and forth from one resonance structure to the other rapidly.
Resonance structure
Usually two way arrows are placed between a molecule's resonance structures to indicate resonance

No, H2O does not have a possible resonance structures.
resonance forms are individual lewis structure in cases where two or more lewis structure are equally good descriptions of a single molecule .
detail of isovalent hypercojugation
Sulfur dioxide has three resonance structures. A singly bonded oxygen would have 3 unshared electron pairs while a doubly bonded oxygen would have 2. The sulfur has one pair.
