Question:

Answer: The melting points of organic compounds are usually lower than those of inorganic compounds.

The boiling points of organic compounds are usually lower than those of inorganic compounds.

Question: Which of the following statements is NOT true about inorganic compounds versus organic compounds?

Answer: Inorganic compounds are generally more flammable than organic compounds.

Question: The compound ((NH4)2CrO4) is used in photography. It forms yellow and monoclinic crystals. Its melting point is 185∘C. It has a high solubility in water, 37.36g100ml. Predict the nature of the compound as organic or inorganic.

Answer: It is inorganic because it contains no carbon.

Question: Ammonium chloride has a water solubility of 383.0gL at 25∘C, and nitroaniline has a water solubility of 800mgL at 25∘C. Identify which are likely to be organic and inorganic compounds from these values.

Answer: Ammonium chloride has a high solubility in water, so it is likely to be an inorganic compound. Nitroanaline is a lot less soluble in water, so it is likely to be organic
