The general reaction is as follows:<\/p>\n<p>R-COOH + HO-R&#8217; \u00e2\u0086\u0092 R-COO-R&#8217; + H2O<\/p>\n<p>In this reaction, R and R&#8217; are alkyl groups. The ester product is a chiral molecule, meaning that it has two non-superimposable mirror images. These mirror images are called enantiomers.<\/p>\n<p>If the acid P and the alcohol Q are both racemic mixtures, then the ester product will also be a racemic mixture. A racemic mixture is a mixture of equal amounts of the two enantiomers.<\/p>\n<p>However, if the acid P or the alcohol Q is a pure enantiomer, then the ester product will also be a pure enantiomer.<\/p>\n<p>In conclusion, the esterification of the acid P with the alcohol Q will give only one enantiomer if the acid P or the alcohol Q is a pure enantiomer. If the acid P and the alcohol Q are both racemic mixtures, then the ester product will also be a racemic mixture.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li>Option A: only one enantiomer. This is the correct answer. As explained above, if the acid P or the alcohol Q is a pure enantiomer, then the ester product will also be a pure enantiomer.<\/li>\n<li>Option B: a mixture of diastereomers. A diastereomer is a stereoisomer that is not an enantiomer. If the acid P and the alcohol Q are both racemic mixtures, then the ester product will be a racemic mixture of diastereomers.<\/li>\n<li>Option C: a mixture of enantiomers. This is not the correct answer. As explained above, if the acid P and the alcohol Q are both racemic mixtures, then the ester product will be a racemic mixture of diastereomers, not a racemic mixture of enantiomers.<\/li>\n<li>Option D: only one diastereomer. This is not the correct answer. As explained above, if the acid P or the alcohol Q is a pure enantiomer, then the ester product will be a pure enantiomer, not a pure diastereomer.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;only one enantiomer&#8221; option2=&#8221;a mixture of diastereomers&#8221; option3=&#8221;a mixture
