The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

. Which of the following compounds is the most soluble in water?<\/strong><\/h3>\n\n\n\n
    \n
  • Answer: C. CH3OH (Methanol)<\/strong><\/li>\n<\/ul>\n\n\n\n

    Explanation:<\/strong>
    Solubility in water depends on the ability of a compound to form hydrogen bonds with water molecules. The more hydrogen bonding a molecule can form, the more soluble it is in water. Here\u2019s a breakdown of each compound:<\/p>\n\n\n\n

      \n
    • A. CH3CH2OH (Ethanol):<\/strong> Ethanol has an -OH (hydroxyl) group, which can form hydrogen bonds with water. It is highly soluble in water, but it is less soluble than methanol due to its larger hydrophobic ethyl group (CH2CH3).<\/li>\n\n\n\n
    • B. CH3CH2CH2OH (Propanol):<\/strong> Propanol also has a hydroxyl group that can hydrogen bond with water. However, the longer hydrophobic chain makes it less soluble in water than ethanol.<\/li>\n\n\n\n
    • C. CH3OH (Methanol):<\/strong> Methanol is the simplest alcohol with a hydroxyl group (-OH) and is the most soluble in water because its small size allows it to form strong hydrogen bonds with water.<\/li>\n\n\n\n
    • D. CH3CH2CH2CH2OH (Butanol):<\/strong> Butanol, while able to form hydrogen bonds, has a longer hydrophobic chain and is less soluble in water compared to the smaller alcohols.<\/li>\n\n\n\n
    • E. CH3CH2CH2CH2CH2OH (Pentanol):<\/strong> Pentanol is less soluble in water because of its larger hydrophobic part.<\/li>\n<\/ul>\n\n\n\n

      Methanol is the most soluble due to its smaller molecular size and higher capacity to form hydrogen bonds with water.<\/p>\n\n\n\n

      \n\n\n\n

      2. What is the general formula for alkenes?<\/strong><\/h3>\n\n\n\n
        \n
      • Answer: E. CnH2n<\/strong><\/li>\n<\/ul>\n\n\n\n

        Explanation:<\/strong>
        Alkenes are hydrocarbons that contain at least one double bond between carbon atoms. The general formula for alkenes is CnH2n<\/strong>, where “n” represents the number of carbon atoms in the molecule. This formula accounts for the two hydrogen atoms that are typically lost due to the presence of a carbon-carbon double bond, compared to alkanes, which follow the formula CnH2n+2<\/strong>.<\/p>\n\n\n\n

        Let\u2019s go over the other options:<\/p>\n\n\n\n

          \n
        • A. CnHn+2:<\/strong> This is the formula for alkanes (saturated hydrocarbons), not alkenes.<\/li>\n\n\n\n
        • B. CnHZn+2:<\/strong> This is incorrect as it doesn\u2019t follow the structure of alkenes or any typical organic compounds.<\/li>\n\n\n\n
        • C. CnHZn:<\/strong> This is not a correct formula for any hydrocarbons.<\/li>\n\n\n\n
        • D. CnHZn-2:<\/strong> This formula is incorrect and doesn’t represent alkenes.<\/li>\n<\/ul>\n\n\n\n

          Thus, the correct formula is CnH2n<\/strong> for alkenes.<\/p>\n\n\n\n

          \n\n\n\n

          3. Which organic compound is saturated?<\/strong><\/h3>\n\n\n\n
            \n
          • Answer: A. Pentane<\/strong><\/li>\n<\/ul>\n\n\n\n

            Explanation:<\/strong>
            Saturated compounds are those in which all carbon-carbon bonds are single bonds, meaning they contain the maximum possible number of hydrogen atoms. Let\u2019s analyze the options:<\/p>\n\n\n\n

              \n
            • A. Pentane (C5H12):<\/strong> Pentane is a straight-chain alkane with all single bonds between carbon atoms, making it saturated.<\/li>\n\n\n\n
            • B. Ethylpentyne:<\/strong> This compound contains a triple bond (as suggested by the “yne” suffix, indicating alkyne), making it unsaturated.<\/li>\n\n\n\n
            • C. Benzene (C6H6):<\/strong> Benzene has a ring structure with alternating single and double bonds, making it unsaturated.<\/li>\n\n\n\n
            • D. Cyclohexyne:<\/strong> The “yne” suffix suggests a triple bond, indicating this is an unsaturated compound.<\/li>\n\n\n\n
            • E. Pentene (C5H10):<\/strong> Pentene contains a double bond, which makes it an unsaturated compound.<\/li>\n<\/ul>\n\n\n\n

              So, pentane<\/strong> is the saturated compound because it contains only single bonds between carbon atoms.<\/p>\n\n\n\n

              \n\n\n\n

              In summary:<\/p>\n\n\n\n

                \n
              1. Most soluble in water: C. CH3OH (Methanol)<\/strong><\/li>\n\n\n\n
              2. General formula for alkenes: E. CnH2n<\/strong><\/li>\n\n\n\n
              3. Saturated compound: A. Pentane<\/strong><\/li>\n<\/ol>\n\n\n\n
