  1. What is the product when a carboxylic acid reacts with an alcohol in the presence of acid catalyst?

    Answer: Ester

    Esterification is the reaction between a carboxylic acid and an alcohol (with H2SO4 catalyst) to produce an ester and water.

  2. Which reagent is used to distinguish between aldehydes and ketones in Tollens' test?

    Answer: Ammoniacal silver nitrate (Tollens' reagent)

    Tollens' reagent (ammoniacal silver nitrate) is reduced by aldehydes to form a silver mirror, but ketones do not react.

  3. What is the hybridization of carbon atoms in ethylene (ethene, CH2=CH2)?

    Answer: sp2

    Each carbon in ethene undergoes sp2 hybridization, forming three sigma bonds and leaving one unhybridized p orbital for the pi bond.

  4. Which reaction mechanism does benzene typically undergo?

    Answer: Electrophilic substitution

    Benzene undergoes electrophilic aromatic substitution (EAS) because addition would destroy the stable aromatic ring system.

  5. What is the functional group present in amines?

    Answer: -NH2

    Amines contain the amino (-NH2) functional group, making them derivatives of ammonia where hydrogen atoms are replaced by organic groups.

  6. Which organic compound is produced by the fermentation of glucose?

    Answer: Ethanol

    Yeast ferments glucose (C6H12O6) anaerobically to produce ethanol (C2H5OH) and carbon dioxide.
