Solved 100% Correct |Verified Answers
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.
The flammability of organic compounds is usually lower than that of
inorganic compounds.
The bond type of organic compounds is more often ionic than for inorganic -
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.
Which of the following statements is NOT true about inorganic compounds versus
organic compounds? - Answer Inorganic compounds are generally more
flammable than organic compounds.
, 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.
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
What type of alkane does not follow the CnH2n+2 formula? - Answer
Cyclic alkanes
Choose the options below that are not characteristics of alkanes.
Linear alkanes have the molecular formula CnH2n.
They have delocalized alternating carbon-carbon single and double bonds.
They interact through attractive van der Waals forces.
They contain only single bonds. - Answer Linear alkanes have the molecular
formula CnH2n.
They have delocalized alternating carbon-carbon single and double bonds.
