Question 4
Consider the reaction CH₂=CH-CH₃ + H₂O → X X + CH₃COOH → Y The structure of Y would be A. CH₃CH₂CHCOOCH₃ CH₃ B. CH₃COOCH₂CH₂CH₃ CH₃
Worked Solution & Example Answer:Consider the reaction CH₂=CH-CH₃ + H₂O → X X + CH₃COOH → Y The structure of Y would be A - VCE - SSCE Chemistry - Question 4 - 2003 - Paper 1
Step 1
Step 2
Determine the reaction of X with CH₃COOH
Answer
Next, we react X (isopropanol) with acetic acid (CH₃COOH). This reaction is a condensation reaction that leads to the formation of an ester. The product Y will be isopropyl acetate (CH₃COOCH(CH₃)₂). Therefore, the structure of Y corresponds to one of the given options.
Step 3
Choose the correct structure for Y
Answer
Among the given options:
A. CH₃CH₂CHCOOCH₃ (This is not correct because it does not match the structure of isopropyl acetate.)
B. CH₃COOCH₂CH₂CH₃ (This is not correct; it implies a linear form with three carbon atoms in the chain instead of two.)
Thus, the correct structure of Y, which is isopropyl acetate, aligns with option D (not provided in the options but would typically be shown in exam format).
