Mock Test 1 — Aldehydes, Ketones and Carboxylic Acids

Aldol condensation needs:

Cannizzaro reaction needs:

Reducing $RCHO$ with NaBH₄ gives:

Strong oxidation of ketone:

Most acidic:

Esterification follows mechanism:

Aldol product of $2CH_3CHO$ on heating:

Wolff-Kishner reduction reduces:

Fehling's test is negative for:

Hell-Volhard-Zelinsky reaction uses:

Number of carbons in acetic acid:

Number of moles of NaOH needed for saponification of ethyl acetate:

Number of $\alpha$-H atoms in acetone:

Assertion (A): $HCHO$ undergoes Cannizzaro reaction but not aldol condensation. Reason (R): $HCHO$ has no $\alpha$-hydrogen.

Assertion (A): Carboxylic acids are stronger acids than phenols. Reason (R): Carboxylate anion is stabilized by two equivalent resonance structures; phenoxide has 4 resonance structures but charge is on less electronegative atoms (carbon).
