Crude oil is blackish colored liquid produced after the decay of organic matter present between
Correct answer: C. sedimentary rocks
- A. earth layer
- B. mountains
- C. sedimentary rocks
- D. rocks
Explanation
Crude oil is formed from the decay and transformation of organic matter, such as marine microorganisms, in sedimentary rocks over millions of years. These rocks, especially source rocks like shale, provide the necessary conditions for the creation and accumulation of hydrocarbons.These rocks are the primary repositories of organic matter that transforms into crude oil over millions of years. Layers of dead plant and animal remains, along with other organic debris, get buried deep under sediment over time. Heat, pressure, and bacterial activity in these sedimentary rocks gradually convert this organic matter into crude oil and natural gas

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
