Answer :

Answer: The molecular formula C7H17 has multiple isomers.

Explanation: 1. Isomers are molecules with the same molecular formula but different structural arrangements. 2. For the molecular formula C7H17, there are different ways the carbon and hydrogen atoms can be arranged to form unique isomeric structures. 3. The number of isomers for a given molecular formula can be determined by exploring the different possible structural arrangements while considering principles of organic chemistry. 4. To determine the exact number of isomers for C7H17, one would need to systematically analyze and draw out the various possible structural configurations based on the given molecular formula. 5. The process of identifying and drawing out the isomeric structures can involve considering different types of isomerism, such as structural isomerism, geometric isomerism, and optical isomerism. 6. By exploring the structural possibilities and applying knowledge of organic chemistry, the total number of isomers for C7H17 can be determined.  In conclusion, the molecular formula C7H17 has multiple isomers due to the various ways in which the carbon and hydrogen atoms can be arranged to form distinct structural configurations.
