The two statements are about the fractional distillation of crude oil. The statements may or may not be correct. They may or may not be linked.
statement 1 Fractional distillation is used to separate crude oil into useful fractions.
statement 2 The fractions with lower boiling points are found at the top of the fractionating column.
What is correct about these two statements?
A Both statements are correct and statement 2 explains statement 1.
B Both statements are correct but statement 2 does not explain statement 1.
C Statement 1 is correct but statement 2 is incorrect.
D Statement 1 is incorrect but statement 2 is correct.
Answer: B
Explaination:
The purpose of fractional distillation is the extraction of crude oil or petroleum into different fractions of alkanes to make it useful. The process through which they separate out or distil off based on their boiling point and length of the HC chain.
