To name the compounds provided in the question, we will follow the IUPAC nomenclature rules for naming alkenes. ### Part A Compound: (E)-3-methyl-3-hexene Explanation: – The prefix “3-methyl” indicates that there is a methyl group attached to the third carbon atom of the parent chain. – The suffix “-ene” indicates that it is an alkene. – The prefix “(E)” indicates the…<\/p>\n\n\n\n

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

Correct Answer:<\/h3>\n\n\n\n

(Z)-2-pentene<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

To determine the correct name for cis-2-pentene<\/strong>, we must follow IUPAC nomenclature rules:<\/p>\n\n\n\n

    \n
  1. Identify the Longest Chain with the Double Bond:<\/strong>\n
      \n
    • The longest continuous chain containing the double bond is pentene<\/strong> (5 carbon atoms, ending in “-ene”).<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Number the Chain to Give the Double Bond the Lowest Number:<\/strong>\n
        \n
      • Numbering from the end closest to the double bond, the double bond starts at C-2<\/strong>, making it 2-pentene<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Assign the Cis\/Trans or E\/Z Notation:<\/strong>\n
          \n
        • “Cis” and “trans” notation is used for simple alkenes, where:\n
            \n
          • Cis<\/strong> means the higher-priority groups (hydrogen in this case) are on the same side of the double bond.<\/li>\n\n\n\n
          • Trans<\/strong> means they are on opposite sides.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
          • IUPAC prefers the E\/Z system<\/strong>, where:\n
              \n
            • Z (zusammen)<\/strong> means the highest priority groups are on the same side (which corresponds to “cis”).<\/li>\n\n\n\n
            • E (entgegen)<\/strong> means they are on opposite sides (which corresponds to “trans”).<\/li>\n<\/ul>\n<\/li>\n\n\n\n
            • In cis-2-pentene<\/strong>, both methyl (-CH3) groups are on the same side, so it is actually (Z)-2-pentene<\/strong>.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

              Image Description:<\/h3>\n\n\n\n

              A structural representation of (Z)-2-pentene<\/strong>, showing:<\/p>\n\n\n\n

                \n
              • A five-carbon chain.<\/li>\n\n\n\n
              • A double bond between C2 and C3.<\/li>\n\n\n\n
              • Methyl (-CH3) groups on the same side<\/strong> of the double bond.<\/li>\n\n\n\n
              • Hydrogen atoms on the same side<\/strong> as well.<\/li>\n<\/ul>\n\n\n\n
