Answer to Question #137377 in Organic Chemistry for Azasha

Question

1.Using the terms condensation and evaporation, explain how naphtha is produced.
2. A hydrocarbon has a boiling point of 200C.
i/ Are its carbon chains shorter,or longer, than those found in naphtha ?
ii/ Is it more viscous, or less viscous, than the compounds found in naptha?

Answer 1

1.

naphtha is obtained by the distillation of oil produced from bituminous shale by destructive distillation. Petroleum naphtha is a name used primarily in the United States for petroleum distillate containing principally aliphatic hydrocarbons and boiling higher than gasoline and lower than kerosene.

2.

 If the boiling point is below 20^oC, then the liquid has already boiled and is a gas.

( i ) Shorter .

( ii )yes this is more volatile than naptha , so , less viscous than naptha .
