Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The primary alcohol found in fermented beverages like wine and beer is ethanol, also known as ethyl alcohol.

Multiple choice
  1. Alkaline KMnO4

  2. Acidified KCr207

  3. H2SO4

  4. a & b both

D Correct answer
Explanation

Both alkaline potassium permanganate (KMnO4) and acidified potassium dichromate (K2Cr2O7) are strong oxidizing agents that can convert primary alcohols to carboxylic acids. Sulfuric acid (H2SO4) is typically used as a dehydrating agent or catalyst, not as an oxidizing agent for this conversion.

Multiple choice
  1. Farnesol

  2. Dolichol

  3. Asparagine

  4. Cytosol

A Correct answer
Explanation

Farnesol is a natural organic compound which is an acyclic sesquiterpene alcohol found as a colourless liquid. It is insoluble in water, but miscible with oils. It is the building block of most, and possibly all, acyclic sesquiterpenoids and is an important starting compound for organic synthesis.

Multiple choice
  1. Feron

  2. Glycol

  3. Glyoxal

  4. TEL

  5. All of these

D Correct answer
Explanation

Anti-knocking agents are those compounds, which on adding gasoline in a very small quantity reduce knocking. TEL (C2H5)4Pb is added the extent of only 0.01% in gasoline as antiknocking compound.

Multiple choice
  1. Acetoacetic acid

  2. Acetone

  3. Succinic acid

  4. Beta-hydroxybutyric acid

  5. -

C Correct answer
Explanation

It is not a ketone body. It is a byproduct in carbohydrate metabolism and is formed in Kreb's cycle.

Multiple choice
  1. hydrogen

  2. methanol

  3. benzene

  4. acetic acid

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Trouton's rule states that the entropy of vaporization for various normal liquids at their boiling points is almost the same constant value, approximately 85-88 J/(K mol). Benzene is a classic non-associated liquid that closely obeys Trouton's rule, whereas liquids with strong hydrogen bonding like water, methanol, and acetic acid show significant deviations.
