Answer:
One way is through fossil fuels. When people burn fossil fuels it enters the atmosphere as carbon dioxide gas. Another way is through animals. Most animals exhale carbon dioxide as a waste product which gets into the atmosphere.
Answer : The name of the given hydrocarbon is, pentane.
Explanation :
The basic rules for naming of organic compounds are :
- First select the longest possible carbon chain.
- For the number of carbon atom, we add prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.
- A suffix '-ane' is added at the end of the name of alkane.
- If two of more similar alkyl groups are present, then the words 'di', 'tri' 'tetra' and so on are used to specify the number of times these alkyl groups appear in the chain.
In the given hydrocarbon, the longest possible carbon chain number is 5 that means we add prefix 'pent' and suffix '-ane'. So, the name of given hydrocarbon will be, pentane.
Hence, the correct option is, pentane.
