ETHER - COMPLETE REVISION in 15 Minute | NEET | JEE | Organic Chemistr Booster

1. Acidic Cleavage (Breaking the Molecule) The most common reaction of ethers is cleavage by strong acids, such as concentrated hydroiodic acid or hydrobromic acid. The Process: The oxygen atom in the ether is protonated by the strong acid, making the bond between oxygen and one of the hydrocarbon groups susceptible to breaking. Products: The ether breaks down into an alkyl halide and an alcohol. Conditions: When heated with an excess of acid, the alcohol produced is often converted into a second molecule of alkyl halide. Structural Impact: If the ether contains a primary or secondary group, it typically follows a substitution mechanism (SN2) where the weaker side is broken. If it contains a tertiary, benzyl, or allyl group, it breaks via a different mechanism (SN1/E1). Limitation: Diaryl ethers (where both sides are aromatic rings) are generally not cleaved 2. Autoxidation (Peroxide Formation) Ethers react slowly with oxygen in the air over time, particularly when exposed to air The Process: Free radical chain formation occurs between the oxygen in the air and the carbon adjacent to the ether oxygen (the alpha-hydrogen). Hazard: This process forms organic hydroperoxides and dialkyl peroxides. Danger: These peroxides are unstable and highly explosive, posing a significant risk if the ether is distilled to dryness. 3. Combustion Ethers are highly flammable liquids. The Reaction: When ignited in the presence of air, they burn to produce carbon dioxide and water. 4. Nucleophilic Substitution Ethers are generally resistant to nucleophiles (substances that attack positive charges) because the alkoxide group is a poor leaving group. However, in specialized, harsh conditions (like with very strong bases such as organolithium compounds), ethers can be cleaved. #organicchemistry #organicchemistry12 #organicbooster #organicchemistryneet #conceptneetdigital #conceptmumbra #conceptneetacademy #neet2026 #neetmumbra #neetchallenge #neetchemistry #neetchemistrycrashcourse #neetbooster #neetchannel #neetchemistryrevision #neetchemistryquestions #neetmotivation #jeemains2026 #jee2026 #jeemains #jeebooster #jeechallenge #jeechemistry #jeechemistryquestions #jeeseries #neetseries #neetbesttrick #ether #hydrolysis
