An organic compound which contains hydrogen and carbon only from the following options:
hydrogen carbide.
hydrocarbon.
organic compound.
hydrocarbide.
Answer to Problem 1AC
Solution:
Option (b) is correct.
Explanation of Solution
Introduction:
A class of compounds containing only carbon and hydrogen is known as hydrocarbons. Hydrocarbons may contain carbon-carbon single, double and triple bonds. Depending on the type of carbon-carbon bonds, hydrocarbons are classified as:
Explanation:
Reason for the correct option:
Hydrocarbon is composed of two words hydrogen and carbon. This represents a class of organic compounds which contains only two elements: hydrogen and carbon. It is a specific type of organic compound which lacks other elements like oxygen, nitrogen or any other elements.
For example: methane
Hence, option (b) is correct.
Reason for the incorrect options:
Option (a) is incorrect because carbides are a class of compounds which contains carbon and a less electronegative element in it. It can be a metal like Fe, W or a metalloid like Si. For example:
Option (c) is incorrect because organic compounds include a class of compounds containing carbon, oxygen, hydrogen, nitrogen etc. Here, carbon is the main element present. So, it is a wrong answer.
Option (d) is incorrect because hydro carbides refer to compounds consisting of hydrogen with carbides. Thus, it may contain any other element than carbon. So, it is a wrong answer.
Hence, options (a), (c) and (d) are incorrect.
Conclusion:
Therefore, an organic compound containing only carbon and hydrogen is hydrocarbon.
