Hydrolysis of sucrose with dilute aqueous sulphuric acid yields

Question

Hydrolysis of sucrose with dilute aqueous sulphuric acid yields (A) 1: 1 D - (+)- glucose; D-(-)-fructose (B) 1: 2 D - ( + )-glucose; D-(-)-fructose (C) 1:1 D-H-glucose; p- (+) -fructose (D) 1:2 D-(-)-glucose; D- (+) -fructose

Tardigrade Admin · Accepted Answer

On hydrolysis with dilute aqueous sulphuric acid, sucrose gives a equimolar mixture of D-(+) glucose and D-(-)-fructose. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/d76251b51ec6e714283fea54c2c427d7-.png" /> Sucrose is dextrorotatory but after hydrolysis gives dextrorotatory glucose and laevorotatory fructose, laevorotatory fructose is more, so the mixture is laevorotatory.

Q. Hydrolysis of sucrose with dilute aqueous sulphuric acid yields

1: 1 D - (+)- glucose; D-(-)-fructose

1: 2 D - ( + )-glucose; D-(-)-fructose

1:1 D-H-glucose; p- (+) -fructose

1:2 D-(-)-glucose; D- (+) -fructose

On hydrolysis with dilute aqueous sulphuric acid, sucrose gives a equimolar mixture of $D - (+)$ glucose and $D - (-)$ -fructose.

Sucrose is dextrorotatory but after hydrolysis gives dextrorotatory glucose and laevorotatory fructose, laevorotatory fructose is more, so the mixture is laevorotatory.

On hydrolysis with dilute aqueous sulphuric acid, sucrose gives a equimolar mixture of D−(+) glucose and D−(−)-fructose. Sucrose is dextrorotatory but after hydrolysis gives dextrorotatory glucose and laevorotatory fructose, laevorotatory fructose is more, so the mixture is laevorotatory.
