Which one of the following is being utilized as a source of biodiesel in the Indian countryside?

  1. Euphorbia

  2. Beetroot

  3. Sugracane

  4. Pongarnia
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Jatropha is a member of the euphorbia family. One of its great selling points as a biofuel is the fact that growing it need not compete with the cultivation of food. The selling point as a bioenergy crop is that it grows in marginal, eroded land, and is resistant to drought.

A petroleum plant is

  1. Sugarcane

  2. Maize

  3. Potato

  4. Euphorbia
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Euphorbia is a petroleum plant. It produces hydrocarbons known as terpenoids which are similar to petroleum. It belongs to Euphorbiaceae family. The latex of this plant can be converted to useful fuels. About 20 tonnes of dry matter per hectare per year is produced by this plant. The latex is converted into natural gas and gasoline. Gasoline is used as an alternative fuel in vehicles.
So, the correct answer is 'Euphorbia'.

Petrocrops are plants

  1. Grown near oil fields

  2. Used in refining crude oil

  3. Whose fossil remains formed crude oil

  4. From which petrol-like fuels can be derived
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Petrocrops are specific plants that produce hydrocarbons similar to petroleum, which can be extracted and refined into fuel. They are not related to the formation of ancient crude oil.

Coal has been mainly formed by 

  1. Bryophytes

  2. Pteridophytes

  3. Angioperms

  4. Algae
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Bryophytes are group of non vascular land plants including hornworts, liverworts and mosses. Peat is a fuel which is produced from dried bryophytes, typically sphagnum. Enormous deposits of peat is accumulated which is later converted into coal.
  • Hence coal has been mainly formed by bryophytes.
  • So,the correct answer is 'Bryophytes'.

The first petroplant discovered by Calvin was

  1. <p>Copaifera longsdorfii</p>

  2. <p>Euphorbia lathyrus</p>

  3. <p>Jatropha</p>

  4. <p>Calotropis</p>
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Calvin started his work on petroplants in 1977. Petroplants produce latex of long hydrocarbon chains which can be converted into petrol like products. He worked on Euphorbia lathyris. When he collected latex from the samples and analysed its composition by different methods like spectroscopy and chromatography, he found long chain hydrocarbons similar to petrol and other fuels. Euphorbia produces large amount of latex which is processed and converted to petrol like fuel.
So, the correct answer is 'Euphorbia lathyris'.

One of the country where alcohol has been very successfully used as motor fuel is?

  1. U.S.A

  2. Brazil

  3. Japan

  4. Germany
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Alcohol has been used as biofuel in many countries especially Brazil. The alcohols that are used as biofuels are methanol, ethanol, propanol and butanol. Ethanol is most commonly used as biofuel. Brazil has highest production of ethanol as biofuel. Ethanol in brazil is produced from sugarcane. The bagasse of sugar cane i.e. residual cane waste is fermented to produce ethanol. In 2015/16, Brazil raised about 80 billion gallons of ethanol. Ethanol is the blended in gasoline and used as fuel for engines.
So, the correct answer is 'Brazil'.

Gasohol was first used in

  1. 1970's

  2. 1980's

  3. 1940's

  4. 1800's
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Gasoline or petrol is a derivative product of petroleum distillation. The ethanol or ethyl alcohol is produced from fermentation and distillation of grains e.g., corn, barley, wheat. When gasoline is blended with ethanol it becomes Gasohol, the percentage is 90 and 10 respectively. It was first used in Nebraska 1940. It is used as an alternative fuel. Hence the first use of Gasohol was in the 1940s.

Hence, the correct answer is '1940's'.
