For each molecular formula, draw all the possible constitutional isomers of alcohols with that formula. Give the IUPAC name for each alcohol.(a) C3H8O(b) C4H10O(c) C3H6O(d) C3H4O
Verified step by step guidance

Step 1: Understand the concept of constitutional isomers. Constitutional isomers are compounds with the same molecular formula but different connectivity of atoms. For alcohols, the functional group is the hydroxyl group (-OH).
Step 2: For each molecular formula, determine the possible carbon skeletons. For example, C3H8O can have a straight chain or a branched chain of carbon atoms.
Step 3: Place the hydroxyl group (-OH) on different carbon atoms in each carbon skeleton to generate different isomers. Ensure that each structure adheres to the valency rules of carbon and oxygen.
Step 4: Draw the structural formulas for each isomer. For example, for C3H8O, you might have 1-propanol and 2-propanol as possible isomers.
Step 5: Assign the IUPAC name to each isomer by identifying the longest carbon chain containing the hydroxyl group and numbering the chain such that the hydroxyl group gets the lowest possible number.

Constitutional Isomers
Constitutional isomers are compounds that have the same molecular formula but differ in the connectivity of their atoms. This means that the arrangement of atoms in the molecule varies, leading to different structural forms. Understanding how to draw and identify these isomers is crucial for determining the various alcohols that can be formed from a given molecular formula.
IUPAC nomenclature is a systematic method for naming organic chemical compounds. It provides a set of rules to derive the names of compounds based on their structure, including the identification of functional groups, the longest carbon chain, and the position of substituents. Mastery of IUPAC naming is essential for accurately communicating the identity of each alcohol isomer.
Alcohols are organic compounds characterized by the presence of one or more hydroxyl (-OH) functional groups. The position and number of these hydroxyl groups influence the properties and classification of the alcohols. Recognizing the role of the hydroxyl group is vital for understanding the behavior and reactivity of the isomers derived from the given molecular formulas.
