Isomer and Natural Gas also Petroleum

Question 1

Isomers

Answer 1

Compound with the same structure formula but different structural formulae called structure isomers.

Question 2

What are two types of structure isomers

Answer 2

Chain isomerism and position isomerism

Question 3

Chain isomerism

Answer 3

Structure of the carbon skeleton differs.
example butane has the same molecular formula as methyl propane but but has a unbranched chain and methyl-propane has a branched chain

Question 4

Position isomerism

Answer 4

Position isomerism is the position of the function group differs.
Example: position has a double bond in pent-ene but different in pent-2-ene position.

Question 5

Petroleum and natural gas

Answer 5

Petroleum ( curve oil) and natural gas are good natural sources of hydrocarbons

Natural gas is mainly methane. It also contains ethane, propane and butane.

Petroleum is a tick mixture of unbranded, branded, ring hydrogen carbon with some natural gas it also dissolved.

Question 6

Fractional distillation of petroleum

Answer 6

Petroleum refining removal of impurities of hydrocarbons and having hydrocarbons mixture into a smaller group of hydrocarbons are called fraction

Each fraction consists of hydrocarbons having a limited range of molar mass and number of carbon atoms

Fractional distillation is carried by using fractionating column
