Thiols, once known as mercaptans, are a family of organic chemicals that contain sulphur. ... Many thiols have strong and repulsive odours.In their pure forms, some thiols are flammable. Thiols are commonly added to natural gas so that people can smell the gas in case of a leak. How do...
Is ethanol flammable? Explain why or why not. Explain the importance of the oil drop experiment. What are the advantages and disadvantages of petroleum as a source of fuel? Why is the gas oil fraction more viscous than the kerosene fraction?
Why do alcohols boil at much higher temperatures than hydrocarbons of similar molecular weight? Why are volatile organic compounds considered hazardous gases? Why are methane and air used in a lime kiln? Why is it preferable to use hydrocarbons or diesel produced by unicellular microbes than what ...
but a double-bonded silicon molecule, unlike double-bonded carbon, is transient – its instability eventually forces it to part into single-bonded silicon atoms. Carbon molecules, such as hydrocarbons, one of the most crucial species of molecules to sustain life, are neither too frail to easily ...
