What odorant is added to LPG to detect the leakage with smell?

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

  1. alcohol

  2. organo sulphur compounds

  3. coal tar

  4. chlorine gas

Show answer
Correct Option: B
Explanation:

As LPG is odourless and the organo-sulphur compound has an unpleasant smell.


Hence, to detect the leakage, ethyl mercaptan (ethanethiol) is added to LPG which is an organo-sulphur compound.

Therefore, option B is correct.

Alcohol, CNG and LPG are ________ substances.

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

  1. gaseous

  2. inflammable

  3. inorganic

  4. none of these

Show answer
Correct Option: B
Explanation:

Alcohol, CNG [Compressed Natural Gas] and LPG [Liquified Petroleum Gas] burn on ignition. So, these three elements are inflammable substances.

Natural gas is composed primarily of:

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

  1. Methane

  2. n-butane

  3. n-octane

  4. a mixture of octanes

Show answer
Correct Option: A
Explanation:

Natural gas is composed mainly composed  of methane, but it also contains small amounts of ethane, propane, butane, and pentane. Methane, a combination of hydrogen and carbon, is formed when plants and animals (organic matter) are present  under the sedimentary layers of the earth.

Hence option A is correct.

Which of the following petroleum product is used for dry cleaning?

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

LPG used as domestic fuel is mixed with a strong smelling volatile liquid for __________.

chemistry fossil fuels petroleum properties of alkanes rocks and minerals

  1. better combustion

  2. good smell/fragrance

  3. detection of gas leakage

  4. higher calorific value

Show answer
Correct Option: C
Explanation:

If the gas leaks in air, it can be easily detected due to smell and preventive measures can be taken. Hence, LPG is mixed with a strong smelling volatile liquid.
