An organic compound X (C7H16O) gives effervescence with Na. X has both enantiomers and diastereomers. X gives yellow precipitate with alkaline iodine solution. With CrO3 - H2SO4 , X is converted into C7H14O (Y) which has enantiom ers but not diastereom ers. X on refluxing with H2SO4 isomerises to Z which neither gives yellow precipitate with alkaline iodine nor changes colour of CrO3 - H2SO4 . What is the minim um number of carbons that can be present in the parent chain of X ?

    Minimum number of carbons in the parent chain of X is 5

    Explanation:
    - The molecular formula of compound X is C7H16O, which suggests that it contains 7 carbon atoms.
    - Effervescence with Na indicates the presence of a carboxylic acid group (COOH) in compound X.
    - The presence of both enantiomers and diastereomers indicates that compound X contains a chiral center or a double bond.
    - Yellow precipitate with alkaline iodine solution suggests the presence of an alcohol group (OH) in compound X.
    - The reaction of X with CrO3 - H2SO4 converts it into compound Y, which has enantiomers but not diastereomers.
    - This indicates that compound Y contains a chiral center, but not a double bond.
    - Refluxing compound X with H2SO4 isomerizes it to compound Z, which does not give a yellow precipitate with alkaline iodine and does not change the color of CrO3 - H2SO4.
    - This suggests that compound Z does not contain an alcohol group and is not a carboxylic acid.
    - Therefore, compound Z must be an alkane or an alkene.
    - Since compound X is isomerized to compound Z on refluxing with H2SO4, it can be inferred that compound X contains a double bond.
    - The only way to have a double bond and a chiral center in a compound with 7 carbon atoms is if the double bond is present in a 5-carbon chain.
    - Hence, the minimum number of carbons in the parent chain of X is 5.

    Conclusion:
    The compound X has a minimum of 5 carbon atoms in its parent chain.
