(a)
Interpretation:
Draw mechanism of formation of poly(ethylene oxide) from ethylene oxide
Concept introduction:
To draw : To draw a mechanism for formation of poly(ethylene oxide)
(b)
Interpretation:
Draw mechanism of formation of poly(ethylene oxide) from ethylene oxide
Concept introduction:
Polymerization is a reaction when monomer molecules are reacted to form a polymer chain. In acidic conditions the epoxide gets protonated and then nucleophilic attack occurs in the epoxide ring opens to form an alcohol. This acts as weak nucleophile and attacks another protonated epoxide ring to extend the carbon chain forming a polymeric chain.
To draw: To draw a mechanism for formation of poly(ethylene oxide) under acidic conditions
(c)
Interpretation:
Draw mechanism of formation of poly(ethylene oxide) from ethylene oxide
Concept introduction:
Polymerization is a reaction when monomer molecules are reacted to form a polymer chain. If the formed polymer is having an ether linkage in it then the monomer must have been a epoxide.
To draw : To draw the structure of monomer required for the synthesis of given polymer.
(d)
Interpretation:
Draw mechanism of formation of poly(ethylene oxide) from ethylene oxide
To determine: To determine whether acidic or basic conditions is used to synthesize the given polymer.
Concept introduction:
Polymerization is a reaction when monomer molecules are reacted to form a polymer chain. If the formed polymer is having an ether linkage in it then the monomer must have been a epoxide.
