Question

28 multiple choice 2 points when an alkene undergoes polymerization, the product is: an ester a polymer an alcohol an alkane

Explanation:

Polymerization is a process where small molecules (monomers) combine to form a large molecule (polymer). Alkenes can undergo polymerization reactions. For example, ethene (\(C_2H_4\)) undergoes polymerization to form polyethylene. The general reaction for the polymerization of alkenes is \(nCH_2 = CH_2
ightarrow[CH_2 - CH_2]_n\), where \(n\) is a large number. In this reaction, the double bond in the alkene is broken, and the monomers are joined together to form a polymer.

An ester is formed from the reaction of an alcohol and a carboxylic acid. An alcohol is formed from the hydration of an alkene (e.g., \(CH_2=CH_2 + H_2O
ightarrow CH_3CH_2OH\) in the presence of an acid catalyst). An alkane can be formed from the hydrogenation of an alkene (\(CH_2 = CH_2+H_2
ightarrow CH_3CH_3\) in the presence of a catalyst like \(Ni\)). But when an alkene undergoes polymerization, the product is a polymer.

Answer:

B. A polymer
