Practice NEET UG Alcohols, Phenols and Ethers in the app →Alcohols are classified as primary (1°), secondary (2°), or tertiary (3°) based on:Glycerol (propane-1,2,3-triol) is classified as:Which compound is the IUPAC name 2-methylbutan-2-ol assigned to?Reduction of a ketone (R₂C=O) with NaBH₄ or LiAlH₄ produces:A Grignard reagent R-MgX reacts with **methanal (HCHO)** to produce, after hydrolysis:A Grignard reagent R'MgX reacts with a **ketone (R₂C=O)** to produce, after hydrolysis:Phenol is industrially manufactured (worldwide majority) from:Ethanol (CH₃CH₂OH, MW 46) has bp 351 K, whereas methoxymethane (CH₃-O-CH₃, MW 46) has bp 248 K. The huge diffeAmong isomeric alcohols (e.g., butan-1-ol, butan-2-ol, 2-methylpropan-2-ol), boiling point order is:Lower alcohols (methanol, ethanol) are completely miscible with water because:Phenol reacts with **NaOH** but ethanol does NOT (with dilute aqueous NaOH). This is because:The dehydration of ethanol with concentrated H₂SO₄ at 443 K gives:The Williamson ether synthesis involves:Phenol gives the iodoform test (yellow precipitate) when treated with I₂/NaOH:Phenol is more acidic than ethanol because:Heating ethanol with concentrated $H_2SO_4$ at $170^\circ$C on the lab burner gives:The Williamson ether synthesis works best with:Hydroboration-oxidation of propene CH$_3$-CH=CH$_2$ on the lab gives:
