A straight-chain organic compound containing an aldehyde functional group has a molecular formula of C5H11CHO. Draw the corresponding skeletal structure. C-H bonds are implied. Select to Draw<\/p>\n\n\n\n

The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The molecular formula C\u2085H\u2081\u2081CHO<\/strong> represents a straight-chain aldehyde. Let’s break this down:<\/p>\n\n\n\n

Step 1: Understanding the Structure<\/strong><\/h3>\n\n\n\n
    \n
  • The “CHO”<\/strong> functional group signifies the presence of an aldehyde (-C(=O)H) functional group<\/strong>.<\/li>\n\n\n\n
  • The remaining part, C\u2085H\u2081\u2081<\/strong>, suggests a pentyl (C\u2085H\u2081\u2081) group<\/strong>.<\/li>\n\n\n\n
  • Since it is a straight-chain<\/strong> compound, it means that the carbon atoms are connected in a single continuous chain without branching.<\/li>\n<\/ul>\n\n\n\n

    Step 2: Identifying the Parent Chain<\/strong><\/h3>\n\n\n\n
      \n
    • The longest carbon chain must include the aldehyde functional group.<\/li>\n\n\n\n
    • The parent chain here is hexanal (six carbon atoms including the aldehyde group).<\/strong><\/li>\n<\/ul>\n\n\n\n

      Step 3: Drawing the Skeletal Structure<\/strong><\/h3>\n\n\n\n
        \n
      • In a skeletal structure:<\/li>\n\n\n\n
      • Carbon atoms are represented by the ends and vertices of lines.<\/li>\n\n\n\n
      • Hydrogen atoms attached to carbon are not explicitly shown<\/strong> (they are implied).<\/li>\n\n\n\n
      • The aldehyde group (-CHO) must be explicitly shown<\/strong> at the end of the chain.<\/li>\n<\/ul>\n\n\n\n

        Here’s the skeletal structure of hexanal<\/strong>:<\/p>\n\n\n\n

              O\n      ||\nCH3-CH2-CH2-CH2-CH2-C-H<\/code><\/pre>\n\n\n\n
        Or in skeletal notation:<\/p>\n\n\n\n
               O\n       ||\n\/\\\/\\\/C-H<\/code><\/pre>\n\n\n\n
        (Each vertex represents a carbon, and the aldehyde functional group is at the terminal end.)<\/p>\n\n\n\n
        Step 4: Explanation<\/strong><\/h3>\n\n\n\n
          \n
        • The structure follows the molecular formula C\u2085H\u2081\u2081CHO<\/strong>.<\/li>\n\n\n\n
        • The aldehyde functional group (-CHO)<\/strong> is always at the end of the chain<\/strong> because aldehydes are terminal functional groups<\/strong>.<\/li>\n\n\n\n
        • The remaining five carbon atoms<\/strong> form a continuous straight chain<\/strong>.<\/li>\n\n\n\n
        • The molecular structure does not include branches<\/strong>, as per the given condition.<\/li>\n<\/ul>\n\n\n\n
          This compound is called hexanal<\/strong>, a simple aldehyde with six carbon atoms.<\/p>\n","protected":false},"excerpt":{"rendered":"
