Find out what structural isomerism is. Start by writing the structure of pentanol. Then draw its structure in different forms by changing the substituents and placing alcohol groups in different positions. Count all the structures to get the answer.Complete step by step solution:- Structural isomers are compounds having the same molecular formula and different structural formulae. This phenomenon is known as structural isomerism.- The structure of pentanol, ${{C}_{5}}{{H}_{11}}OH$ is $C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}OH$.- Now, the question says the number of structural isomers of alcohol. So, the functional group needs to be alcohol only in all the isomers.- Let’s draw all the possible structural isomers of pentanol. - There are eight structural isomeric alcohols of pentanol.- They are as follows:- Pentan-1-ol- Pentan-2-ol- Pentan-3-ol- neo-pentanol- 2-methylbutan-1-ol- iso-pentanol- 3-methylbutan-2-ol- 2-methylbutan-2-ol- Therefore, alcoholic structural isomers having the molecular formula, ${{C}_{5}}{{H}_{11}}OH$ are eight.Therefore, the correct answer is option C.Note: Remember structural isomers are the compounds having the same molecular formula but different structural formulae. For alcohols, ethers are also structural isomers. So, ${{C}_{5}}{{H}_{11}}OH$ also has more structural isomers. Depending on the way of structural arrangement of atoms, more isomers of ${{C}_{5}}{{H}_{11}}OH$ are ethyl propyl ether, butyl methyl ether, ethyl isopropyl ether, tert-butyl methyl ether, iso-butyl methyl ether, etc.Recently Updated PagesBasicity of sulphurous acid and sulphuric acid areMaster Class 12 English: Engaging Questions & Answers for SuccessMaster Class 12 Social Science: Engaging Questions & Answers for SuccessMaster Class 12 Maths: Engaging Questions & Answers for SuccessMaster Class 12 Economics: Engaging Questions & Answers for SuccessMaster Class 12 Physics: Engaging Questions & Answers for SuccessBasicity of sulphurous acid and sulphuric acid areMaster Class 12 English: Engaging Questions & Answers for SuccessMaster Class 12 Social Science: Engaging Questions & Answers for SuccessMaster Class 12 Maths: Engaging Questions & Answers for SuccessMaster Class 12 Economics: Engaging Questions & Answers for SuccessMaster Class 12 Physics: Engaging Questions & Answers for Success
