PTT (polytrimethylene terephthalate) is a polyester formed from 1,3-propanediol (HOCH 2CH 2CH 2OH) by the given reaction. PTT is sold under the trade name Sorona by DuPont. 1,3-Propanediol can now be made from a plant source like corn, rather than from petroleum starting materials. This makes PTT a more environmentally friendly polyester than PET. What is the structure of PTT?
Give two reasons relating to your chemical knowledge why dichlorodimethylsilane is a useful starting material for the formation of methyl silicone polymers
Must stereochemistry be considered when synthesizing ethylene glycol from ethene? Explain.
Esterication is the reaction of a carboxylic acid (RCOOH) with an alcohol (R'OH) to form an ester (RCOOR') with loss of water. Equation [1] is an example of an intermolecular esterication reaction. Equation [2] is an example of an intramolecular esterication reaction; that is, the carboxylic acid and alcohol are contained in the same starting material, forming a cyclic ester as product. The equilibrium constants for both reactions are given. Explain why Keq is different for these two apparently similar reactions.

Q14 Which statement among the following is incorrect concerning the oxidation or reduction of organic molecules? -Oxidation of alcohols is usually done under acidic or basic conditions to facilitate electron transfer. b- PCC will not oxidize an aldehyde to a carboxylic acid. -All alcohols can be oxidized to form one of an aldehyde, ketone, or carboxylic acid. Reaction of a ketone with a Grignard reagent in ether, followed by dilute acid work-up, produces a tertiary alcohol.
