324575 Acid hydrolysis of sucrose causes

1 Esterification
2 Saponification
3 Inversion
4 Rosenmund reduction
CHXII14:BIOMOLECULES

324576 The correct statement about the following disaccharide is
supporting img

1 Ring (i) is pyranose with \(\mathrm{\alpha}\)-glycosidic link
2 Ring (ii) is furanose with \(\mathrm{\alpha}\)-glycosidic link
3 Ring (i) is furanose with \(\mathrm{\alpha}\)-glycosidic link
4 Ring (ii) is pyranose with \(\mathrm{\beta}\)-glycosidic link
CHXII14:BIOMOLECULES

324577 Assertion :
Sucrose is called as invert sugar.
Reason :
On hydrolysis, sucrose bring the change in the sign of rotation from dextro \(\mathrm{(+)}\) to laevo (-)

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
CHXII14:BIOMOLECULES

324578 Assertion :
A solution of sucrose in water is dextrorotatory. But on hydrolysis in the presence of a little hydrochloric acid, it becomes laevorotatory.
Reason :
Sucrose on hydrolysis gives unequal amounts of glucose and fructose. As a result of this, change in sign of rotation is observed.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
