324566 Sucrose is dextrorotatory but after hydrolysis the mixture show laevorotation, this is because of

1 Racemic mixture is formed
2 Laevorotation of fructose is more than dextrorotation of glucose
3 Laevorotation of glucose is more than dextrorotation of fructose.
4 Sucrose is a non-reducing sugar
CHXII14:BIOMOLECULES

324567 The change in optical rotation of freshly prepared solution of cane sugar with time is known as

1 mutarotation
2 inversion
3 specific rotation
4 rotatory motion
CHXII14:BIOMOLECULES

324568 Assertion :
The specific rotation of a freshly prepared solution of \(\alpha\)-glucose decreases from \(+112^{\circ}\) to \(52.7^{\circ}\) while that of \(\beta\)-glucose increases from \(+19^{\circ}\) to \(52.7^{\circ}\).
Reason :
The change in specific rotation of an optically active compound with time to an equilibrium value is called mutarotation.

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

324569 Statement A :
