A) Sucrose
B) Enzyme
C) Starch
D) Teflon
Correct Answer: A
Solution :
(i) Teflon is polymer of tetrafluoroethylene \[(C{{F}_{2}}=C{{F}_{2}})\] (ii) Starch is polymer having formula\[{{({{C}_{6}}{{H}_{10}}{{O}_{5}})}_{n}}\] (iii) Enzymes are proteins made of polypeptides. (iv) Sucrose \[({{C}_{12}}{{H}_{22}}{{O}_{11}})\] is a disaccharide. It gives two molecules of monosaccharides on hydrolysis. It is not polymer but it is dimer. \[\underset{sucrose}{\mathop{{{C}_{12}}{{H}_{22}}{{O}_{11}}}}\,+{{H}_{2}}O\xrightarrow{{{H}^{+}}/invertase}\underset{glucose}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\]\[\underset{fructose}{\mathop{+{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\]
