For \(\mathrm{(+)}\) lactose the incorrect statement is
1 \(\mathrm{(+)}\) lactose, \(\mathrm{\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11}}\) contains \(\mathrm{8-\mathrm{OH}}\) groups
2 On hydrolysis (+) lactose gives equal amount of D (+) glucose and D (+) galactose
3 ( + ) lactose is a \(\mathrm{\beta}\)-glycoside formed by the union of molecule of \(\mathrm{\mathrm{D}(+)}\) glucose and a molecule of \(\mathrm{\mathrm{D}(+)}\) galactose.
4 (+) lactose is reducing sugar and does not exhibit mutarotation

Assertion : Maltose is a reducing sugar which gives two moles of D - glucose on hydrolysis Reason : Maltose has a \(1,4-\beta-\) glycosidic linkage.
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 Both Assertion and Reason are correct.
Explanation:
Maltose, a disaccharide \(\left(\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11}\right)\) is a reducing sugar, which upon hydrolysis yields two moles of D- \((+)\) - glucose. In maltose, the two D - glucose units are linked through \(\alpha\)-glycosidic linkage between \(\mathrm{C}-1\) of a glucose unit and \(\mathrm{C}-4\) of the other. So, Assertion is true and reason is false.

Assertion : \(\mathrm{\beta}\)-glycosidic linkage is present in maltose, Reason : Maltose is composed of two glucose units in which C-1 of one glucose unit is linked to C-4 of another glucose unit.
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.
Explanation:
Maltose is composed of two \(\mathrm{\alpha}\)-D-glucose units in which \(\mathrm{\mathrm{C} 1}\) of one glucose unit (I) is linked to \(\mathrm{\mathrm{C} 4}\) of another glucose unit (II).
