  1. Which reducing agent selectively reduces a ketone to a secondary alcohol?

    Answer: NaBH4

    NaBH4 is a mild reducing agent that converts ketones into secondary alcohols.

  2. Glycogen is a storage polymer made of which monomer?

    Answer: Glucose

    Glycogen is a branched polysaccharide of glucose units stored in liver and muscle.

  3. What distinguishes cis and trans isomers?

    Answer: Arrangement of groups around a double bond

    Cis/trans isomers differ in the spatial arrangement of groups across a restricted double bond.

  4. Which element, besides C, H, and O, is always found in proteins?

    Answer: Nitrogen

    Proteins always contain nitrogen because amino acids have amino groups.

  5. The functional group -O- linking two carbon groups defines an:

    Answer: Ether

    An ether features an oxygen atom bonded between two carbon-containing groups.

  6. Which process breaks polymers into monomers using water?

    Answer: Hydrolysis

    Hydrolysis cleaves bonds in polymers by adding water.

  7. Unsaturated fatty acids differ from saturated ones because they contain:

    Answer: Carbon-carbon double bonds

    Unsaturated fatty acids contain one or more C=C double bonds, lowering their melting point.
