The sigma (σ) bond between the oxygen of the –OH group and carbon in alcohols is a single covalent bond formed by the overlap of atomic orbitals. The bond angle is slightly less than the tetrahedral angle (109.5 degrees) due to the presence of a lone pair on the oxygen atom. The lone pair exerts greater repulsion than bonding electron pairs, leading to a compressed bond angle. This deviation from the ideal tetrahedral angle is known as the VSEPR (Valence Shell Electron Pair Repulsion) theory, which explains the geometric arrangement of atoms around a central atom based on minimizing repulsion between electron pairs.
The carbon–oxygen (C–O) bond length in phenol is slightly less than that in methanol due to resonance effects.

The carbon–oxygen (C–O) bond length in phenol is slightly less than that in methanol due to resonance effects. Phenol exhibits resonance structures, leading to electron delocalization within the aromatic ring. This resonance contributes to partial double-bond character in the C–O bond, shortening the bond length. In contrast, methanol lacks resonance stabilization, resulting in a more straightforward single bond. The delocalization of electrons in phenol makes the C–O bond stronger and shorter compared to the single bond in methanol, where electrons are localized between the carbon and oxygen atoms, causing a longer bond length.

Primary, secondary, and tertiary alcohols are classified based on the carbon atom to which the hydroxyl (-OH) group is attached. In primary alcohols, the hydroxyl group is bonded to a carbon atom that is connected to only one other carbon. Secondary alcohols have the hydroxyl group attached to a carbon atom linked to two other carbons, while tertiary alcohols have the hydroxyl group bonded to a carbon atom connected to three other carbons. This classification is vital because it influences the reactivity and physical properties of alcohols, with primary alcohols often exhibiting distinct behavior compared to secondary and tertiary counterparts.

In the IUPAC system, alcohols are named by identifying the longest continuous carbon chain containing the hydroxyl (-OH) group, which becomes the parent chain. The parent chain’s name is derived from the corresponding alkane by changing the “-ane” ending to “-anol.” Substituent positions are indicated by assigning the lowest possible number to the carbon atom bearing the hydroxyl group. If there are multiple substituents, their locations are specified using numerical prefixes. For example, in 3-methyl-1-butanol, the hydroxyl group is on the third carbon of a four-carbon chain, and there is a methyl group on the first carbon.
Polyhydric alcohols, which have more than one hydroxyl (-OH) group, are named by specifying the parent hydrocarbon chain and indicating the number of hydroxyl groups.

Polyhydric alcohols, which have more than one hydroxyl (-OH) group, are named by specifying the parent hydrocarbon chain and indicating the number of hydroxyl groups. The “-ol” suffix is used, and numerical prefixes indicate the quantity of hydroxyl groups. For example, the IUPAC name for glycerol, a triol, is 1,2,3-propanetriol. In cyclic alcohols, the ring is designated as the parent structure, and the hydroxyl group’s position is indicated by the lowest possible number. For instance, cyclohexanol is the IUPAC name for a six-membered ring with an attached hydroxyl group on one of the carbons.

ATP drives endothermic reactions in the cell by releasing energy stored in its high-energy phosphate bonds. In endothermic reactions, where energy is absorbed, ATP hydrolysis occurs, breaking one of ATP’s phosphate bonds to form adenosine diphosphate (ADP) and inorganic phosphate (Pi). This reaction releases energy that is utilized to fuel energy-consuming processes. The released energy provides the necessary activation energy for endothermic reactions to proceed, facilitating cellular functions like active transport, biosynthesis, and muscle contraction. The cycling between ATP and ADP ensures a continuous supply of energy for endothermic reactions essential for cellular activities.

Aerobic organisms require a sufficient intake of oxygen because it is crucial for the process of aerobic respiration. Aerobic respiration, which occurs in the presence of oxygen, is highly efficient in extracting energy from glucose and other nutrients, yielding a large amount of ATP. Oxygen serves as the final electron acceptor in the electron transport chain during oxidative phosphorylation, allowing the complete breakdown of pyruvate and maximizing ATP production. Without sufficient oxygen, cells resort to less efficient anaerobic pathways, leading to lower ATP yields and the accumulation of byproducts like lactic acid. Adequate oxygen intake is essential for optimizing energy production and cellular function in aerobic organisms.
