Answer the question on the basis of passage given below :
Living systems are made up of various complex bio-molecules like carbohydrates, proteins, nucleic acids, lipids etc. Proteins and carbohydrates are essential constituents of our food. Carbohydrates are primarily produced by plants and form a very large group of naturally occurring organic compounds. Some common examples are cane sugar, glucose, starch etc.
Which of the following is a structural component of starch?

Read the passage carefully and answer the questions based on the passage:
The number of reacting species (atoms, ions or molecules) taking part in an elementary reaction, which must collide simultaneously in order to bring about a chemical reaction is called molecularity of a reaction. In the rate equation Rate \(=k[\mathrm{~A}]^x[\mathrm{~B}]^y\)
\(x\) and \(y\) indicate how sensitive the rate is to the change in concentration of A and B, respectively. Sum of these exponents, i.e., \(x +y\) gives the overall order of a reaction where \(x\) and \(y\) represent the order with respect to the reactants A and B respectively. Hence, the sum of powers of the concentration of the reactants in the rate law expression is called the order of that chemical reaction. For a first order reaction, the concentration of the reactant varies as \([\mathrm{R}]=[\mathrm{R}]_0 e^{-k t}\)
Which of the following is a zero order reaction?

What will be the increasing order of basic strength of the following compounds?
\(C_2 H_5 NH_2,\left(C_2 H_5\right)_2 NH,\left(C_2 H_5\right)_3 N, C_6 H_5 NH_2\)

Arrange the following in decreasing order of the number of molecules contained in:
(A) \(1 6 ~ g\) of \(O _2\)
(B) \(1 6 ~ g\) of \(CO _2\)
(C) \(1 6 ~ g\) of \(CO ^{-}\)
(D) \(16 g of H _2\)
Choose the correct order:
