Mock Test 1 — Alcohols, Phenols and Ethers

Glycerol contains:

Methanol on $Cu/573K$:

$3°$ alcohols don't oxidize easily because:

Acidity order:

Test for phenol (color):

Reimer-Tiemann reagent:

Kolbe-Schmitt produces:

Anisole + HI cleavage gives:

Boiling point order: ethanol vs dimethyl ether (same M):

Most acidic among monohydric alcohols:

Number of -OH groups in glycerol:

Number of carbons in anisole:

Number of moles of $Br_2$ needed to give 2,4,6-tribromophenol from phenol:

Assertion (A): Phenol is more acidic than ethanol. Reason (R): Phenoxide ion is resonance-stabilized while ethoxide is not.

Assertion (A): Williamson synthesis does not work well for $3°$ alkyl halides. Reason (R): $3°$ halides undergo elimination ($E_2$) preferentially when treated with strong bases/nucleophiles like alkoxides.
