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

  1. TEL

  2. $C _2H _5OH$
  3. Glyoxal

  4. Freon

A Correct answer
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:

  1. fractional distillation

  2. liquation

  3. concentration

  4. filtration

A Correct answer
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.

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

  1. $C _6$ to $C _{10}$
  2. $C _8$ to $C _{12}$
  3. $C _{11}$ to $C _{16}$
  4. $C _{18}$ to $C _{22}$
Reveal answer Fill a bubble to check yourself
C Correct answer
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.
