Which of the following is used as an anti -knocking compound?

chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. TEL

  2. $C _2H _5OH$

  3. Glyoxal

  4. Freon

Show answer
Correct Option: A
Explanation:

An anti-knocking agent is the substance which is used to reduce the engine knocking. It increases the octane number of the fuel. It helps in auto-ignition by raising the temperature and pressure. TEL is tetraethyl Lead which is used as an Anti-Knocking compound.

The first step in refining petroleum is:

chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. fractional distillation

  2. liquation

  3. concentration

  4. filtration

Show answer
Correct Option: A
Explanation:

The very first step in the refining of petroleum oil is Fractional distillation i.e, the fractionation of crude oil in atmospheric vacuum distillation towers. 

The first process in a petroleum refinery is known as distillation. In this process, crude oil is heated and filled into a distillation column.

Which of the following is not obtained on fractional distillation of petroleum?

chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. Paraffin wax

  2. Asphalt

  3. Coal gas

  4. Petroleum gas

Show answer
Correct Option: C
Explanation:

Fractional distillation of petroleum gives paraffin wax, asphalt, crude oil. While fractional distillation of coal gives coal gas.

All are the mixtures of various organic compounds except:

chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. petrol/diesel

  2. octane

  3. vaseline

  4. kerosene

Show answer
Correct Option: B
Explanation:

All of the given substances are mixtures of various organic compounds except octane. Because octane is a pure saturated hydrocarbon containing 8 carbon atoms.

Kerosene oil is a mixture of hydrocarbons which contains the number of carbon atoms is:

chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. $C _6$ to $C _{10}$

  2. $C _8$ to $C _{12}$

  3. $C _{11}$ to $C _{16}$

  4. $C _{18}$ to $C _{22}$

Show answer
Correct Option: C
Explanation:

Kerosene is a mixture of hydrocarbons. The chemical composition depends on its source of isolation, usually, it consists of about 10 different hydrocarbons, each containing 11 to 16 carbon atoms per molecule. 

The main constituents are saturated straight-chain and branched-chain hydrocarbons which are also called as paraffin, as well as ring-shaped cycloparaffins which are also known as naphthenes. Kerosene is less volatile liquid than gasoline.

Paraffin wax is used for making:

chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. vaselines

  2. candles

  3. greases

  4. all of the above

Show answer
Correct Option: D
Explanation:

Paraffin wax is derived from petroleum,coal that consist of a mixture of hydrocarbon molecules between 20-40 carbon atoms. Common applications of paraffin include lubrication,candles,electrical insulation. It is insoluble in water but soluble in ether,alcohol or benzene.

Identify the odd one out from the following.

chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. diesel

  2. kerosene

  3. methanol

  4. petrol

Show answer
Correct Option: C
Explanation:

Methanol is the odd one because the rest are fractions of petroleum.

The fraction of petroleum used as jet fuel is:

chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. petrol

  2. kerosene

  3. diesel

  4. alcohol

Show answer
Correct Option: B
Explanation:

Jet fuel is a clear to straw colored fuel based on either an unleaded kerosene or a naphtha kerosene blend. It is similar to diesel fuel and can be used in either compression ignition engines or turbine engines.
