324817 A polysaccharide ' \(\mathrm{\mathrm{X}}\) ' on boiling with dil \(\mathrm{\mathrm{H}_{2} \mathrm{SO}_{4}}\) at \(\mathrm{393 \mathrm{~K}}\) under 2-3 atm pressure yields ' \(\mathrm{\mathrm{Y}}\) '. ' \(\mathrm{\mathrm{Y}}\) ' on treatment with bromine water gives gluconic acid. ' \(\mathrm{\mathrm{X}}\) ' contains \(\mathrm{\beta}\)-glycosidic linkages only. Compound ' \(\mathrm{\mathrm{X}}\) ' is :

1 starch
2 cellulose
3 amylose
4 amylopectin

324819 The difference between amylose and amylopectin is

1 Amylopectin have \(\mathrm{1 \rightarrow 4 \alpha}\) - linkage and \(\mathrm{1 \rightarrow 6 \beta}\) - linkage
2 Amylose is made up of glucose and galactose
3 Amylose have \(\mathrm{1 \rightarrow 4 \alpha}\) - linkage and \(\mathrm{1 \rightarrow 6 \beta}\) - linkage
4 Amylopectin have \(\mathrm{1 \rightarrow 4 \alpha}\) - linkage and \(\mathrm{1 \rightarrow 6 \alpha}\) - linkage.
