Step 1
Which row of the table correctly matches the polymer with its structural feature and property?
Answer
To determine the correct match, we analyze each option regarding the reactions involved in polymer formation or breakdown.
-
Option A: Hydration of ethene (C2H4) in dilute acid yields ethanol (C2H5OH), not hexane (C2H6). So, this option is incorrect.
-
Option B: Hydration of ethene (C2H4) with concentrated acid would yield ethanol (C2H5OH), but this does not match the polymer indicated. Therefore, this option is also incorrect.
-
Option C: Dehydration of ethanol (C2H5OH) using dilute acid results in ethene (C2H4). This option correctly matches the process.
-
Option D: Dehydration of C2H4 with water in concentrated acid would not produce a meaningful polymerization or result in the stated products; thus, this option is incorrect.
After analysis, the correct answer is C: Dehydration of C2H5OH with dilute acid results in C2H4.
