Fractions of crude oil​

Fractions. There are several ways of classifying the useful fractions that are distilled from crude oil. One general way is by dividing into three categories: light, middle, and heavy fractions. Heavier components condense at higher temperatures and are removed at the bottom of the column.

Fraction:No. of carbon atoms:Boiling point range oC:

Gasoline (petrol)4 - 12                   32-160oC

Kerosine (paraffin)11 - 15            160-250oC

Diesel oil         15 - 19               220-350oC

Residue lubricating oil heavy fuel oil bitumenCAbove 350oC

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
