This means that there will be no problem in numbering the carbon atoms as well as in choosing the main carbon chain. After identifying the root word, write the suffix for alkene in accordance to the IUPAC conventions and nomenclature.Complete Solution :There are few rules to be followed to name a compound. Let us see those. -Find the parent hydrocarbon.Firstly, we have to choose the longest chain. If two different chains of equal length are present, choose the one which has the most substituents. Here there is only one chain in the compound.-Count the number of carbon atoms present in the chain. IUPAC have fixed some prefixes based on the number of carbon atoms.Example for 1 carbon atom, the prefix is “meth”. For 2 carbon – “eth”, “prop” for 3, “but” for 4, “pent” for 5 and so on.There are 4 carbon atoms in $C{H_3} - CH = CH - C{H_3}$. So, the prefix is “But”.- See if there is any double or triple bond, functional group, substituent in the main chain. Then start counting from that side from which it comes on the lowest number.In this case, there is a double bond between the carbon atoms 2 and 3. So the suffix is “ene”.-Name the compound. The name of the compound is 2-butene.So, the correct answer is “Option D”.Note: In the above question it was easy to choose the longest carbon chain and the main functional group. However, when we have to choose between the main functional group and longest chain, we give priority to the functional group. The above explanation is shown below: For the above organic compound, the IUPAC name is 2-ethylethan 1,3-dioic acid.Recently Updated PagesMaster Class 10 Computer Science: Engaging Questions & Answers for SuccessMaster Class 10 General Knowledge: Engaging Questions & Answers for SuccessMaster Class 10 English: Engaging Questions & Answers for SuccessMaster Class 10 Social Science: Engaging Questions & Answers for SuccessMaster Class 10 Maths: Engaging Questions & Answers for SuccessMaster Class 10 Science: Engaging Questions & Answers for SuccessMaster Class 10 Computer Science: Engaging Questions & Answers for SuccessMaster Class 10 General Knowledge: Engaging Questions & Answers for SuccessMaster Class 10 English: Engaging Questions & Answers for SuccessMaster Class 10 Social Science: Engaging Questions & Answers for SuccessMaster Class 10 Maths: Engaging Questions & Answers for SuccessMaster Class 10 Science: Engaging Questions & Answers for Success
