Given below are two statements:
Statement I: D-(+)-glucose + D-(+) fructose $\xrightarrow{-\mathrm{H}_2 \mathrm{O}}$ Sucrose
$$\text { sucrose } \xrightarrow{\text { hydrolysis }} \mathrm{D}-(+) \text { glucose }+\mathrm{D}-(+) \text { fructose }$$
Statement II: Invert sugar is formed during sucrose hydrolysis
In the light of the above statements, choose the correct answer from the options given below
Solution
<p>In Statement I, the reaction shown is incorrect. During the hydrolysis of sucrose, D-(+)-glucose and D-(-)-fructose are produced. However, the statement incorrectly specifies D-(+)-fructose, making Statement I inaccurate.</p>
<p>Statement II is accurate. When sucrose undergoes hydrolysis, it results in the formation of invert sugar, a mixture of glucose and fructose. This change involves the inversion of optical rotation, which is where the term "invert sugar" comes from.</p>
