  • False, Fats are solid at room temperature.
  • False, Ethylamine is liquid at room temperature due to intermolecular hydrogen bonding in its solution.
  • False Tristearin (a triglyceride) has 57 carbon atoms (Molecular Formula: C57H110O6).
  • True, Aniline reacts with bromine water forming a white precipitate of 2,4,6-tribromoaniline.
  • True, Fatty Acids are carboxylic acids with long unbranched chain of hydrocarbon.
  • True, Monosaccharides ( basic unit of all carbohydrates ) has 6 -OH groups.
  • True, Aniline has moderate solubility in water due to the presence of a big hydrophobic group (phenyl).
  • False, Methyl Propionate has a rum-like smell (smell of ripen grapes).

Thus, There are 4 correct facts.
