Hybridization is defined as the mixing of the atomic orbitals belonging to the same atom but having slightly different energies so that a redistribution of energy takes place between them resulting in the formation of new orbitals of equal energies and identical shapes. The new orbitals thus formed are known as hybrid orbitals.

The rib cage is a bony and cartilaginous structure. A typical rib cage consists of 24 ribs (12 pairs), the sternum (an inverted T-shaped structure connecting the rib bones), costal cartilages and the 12 thoracic vertebrae shown in the diagram below. The first seven pairs of ribs connect directly to the sternum and are referred to as true ribs. The remaining five pairs of ribs do not connect directly to the sternum and are referred to as false ribs. The rib cage aids in the protection of the heart and lungs.

The acidic strength of phenols is affected by the presence of substituents on the ring.
An electron-withdrawing group increases the acidic strength by greater dispersal of the negative charge on the phenoxide ion by inductive effect (-I) or by resonance (-R) effect.
An electron-donating group decreases the acidic strength due to (+I) or (+R) or both.
Halogens have +R and -I effects, but the -I effect is more dominant.
Therefore, all halophenols are more acidic(except p-fluorophenol) than phenol itself.
