\([B]\) on heating with sulphuric acid gives compound \([C]\) which forms monozonide \([D]\). The compound \([D]\) on hydrolysis in the presence of zinc dust gives compound \([E]\). Compound \([E]\)
on oxidation gives \(C _2 H _4 O _2\) [F]
Identify Compound [A]

Read the passage carefully and answer the questions
Carbohydrates are naturally formed organic compounds from various plants. The common chemical formula, \(C _x\left( H _2 O \right)_y\), was considered as hydrates of carbon to derive the various carbohydrates. For instance, the general formula for glucose ( \(C _6 H _{12} O _6\) ) easily fits into the above formula. Carbohydrates also called saccharides are classified on the basis of their behavior towards hydrolysis. Monosaccharides cannot be hydrolyzed further to simpler units of polyhydroxy aldehyde or ketones. About 20 monosaccharides are known to occur in nature. Carbohydrates that yield large number of monosaccharide units are called polysaccharides. Amino acids contain ( \(- NH _2\) ) and ( - COOH ), which can be classified in various forms. Proteins are polymers of alpha amino acids which are connected to each other by a peptide bond or peptide linkage. When a native protein is subjected to physical change, its globules unfold and helix get uncoiled and the protein loses its biological activity. The protein is said to be denaturated.
Which of the following statements is incorrect for Lactose ?

Which of the following reactions is the most suitable for the preparation of n-propylbenzene?

Name the reaction when Benzene is treated with ethanoyl chloride in the presence of anhydrous AlCl\(_3\)

A carrier wave \(C(t) = A_c \sin \omega_c t\) is amplitude modulated by modulating signal \(m(t) = A_m \sin \omega_m t\). The maximum and minimum amplitudes of the modulated wave are found to be 20 V and 5 V respectively. The modulation index is:

\(\int \frac{d x}{\sqrt{5-x}}=\) (where \(C\) is arbitrary constant.)

An infinite line of charge has a linear charge density of \(10^{-7} \text{ C m}^{-1}\). The magnitude of the force acting on a charge \(6.4 \times 10^{-19} \text{ C}\) kept at a distance of 8 cm from the line of charge is
