Abstract:
Long-standing, heavy alcohol use can lead to alcohol dependence, which predisposes to alcohol withdrawal if alcohol consumption is suddenly decreased or stopped. Alcohol withdrawal syndrome is characterized by a hyperadrenergic response, with symptoms ranging from mild tremulousness to delirium tremens. We report a 55-year-old male presenting with hyperthermia, tachycardia, tachypnea, altered consciousness, tremors, rigidity, diaphoresis, elevated creatinine kinase, and myoglobinuria. The diagnosis of alcohol withdrawal was made due to a history of alcohol use disorder with the last drink two days ago and no history of any medication or drug intake prior to admission. He was treated with benzodiazepines with an improvement in his condition.

Oxidation of Alcohols
The process of oxidation in a chemical reaction is observed in any of the three forms:
Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.
Protection of Alcohols
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...

Preparation of Alcohols via Substitution Reactions
Alcohols can be synthesized from alkyl halides via nucleophilic substitution reactions. The highly polar carbon-halogen bond in the substrate makes halide a good leaving group. The hydroxide ion or water can act as a nucleophile to take the place of halide and form an alcohol. The substitution reactions occur via two different reaction pathways, SN1 or SN2, depending on the nature of carbon attached to the halide.
Primary alcohols are synthesized from primary alkyl halides, and the...
Esters to Alcohols: Hydride Reductions
Lithium aluminum hydride is a source of hydride ions and functions as a nucleophile. The mechanism proceeds in three steps. Firstly, the nucleophilic hydride ion attacks the carbonyl carbon of the ester to form a tetrahedral intermediate. Subsequently, the carbonyl group re-forms,...
