Addition of `O_(2)` on ethylene in presence of Ag at `200^(0)C` forms
A epoxyetheane
B oxirane
c) cyclic ether
all of these

An organic compound A on heating with concentrated H_(2)SO_(4) forms a compound B which on addition of one mole of hydrogen in presence of Ni forms a compounds C. One mole od compound C on combustion form two moles of CO_(2) and three moles of H_(2)O . Identify the compounds A,B and C write the chemical equation of the reactions involved.

Abscission zone is characterized by (a) Presence of callose plugs (b) Presence of a distinct layer (c) Activity of celluloses and pectinases (d) All of these

Match the compounds (A) ethanol, (B) methane, (C) ethanoic acid, (D) ethyne and (E) ethene with the descriptions given below: It forms methanol on oxidation in the presence of copper at 200^@C .

Read the following four statement A,B,C and D and select the right option having both correct statements. statements (A) Z scheme of light reaction takes place in presence of PS I only . (B) Only PS I is functional in cyclic photosporylation (C) Cyclic photophosphorylation results into synthesis of ATP and NADPH_(2) (D) Stroma lamellae lack PSII as well as NADP (a) A and B (b) B and C (c) C and D (d) B and D

Statement I: If A,B,C,D are angles of a cyclic quadrilateral then sum sin A=0. Statement II: If A, B, C, D are angles of cyclic quadrilateral then sum cos A=0.

The K_(SP) of Ag_(2)C_(2)O_(4) at 25^(@)C is 1.29xx10^(-11)mol^(3)L^(-3) . A solution of K_(2)C_(2)O_(4) containing 0.152 mole in 500 mL water is shaken at 25^(@)C with excess of Ag_(2)CO_(3) till the equilbirium is reached. Ag_(2)CO_(3)+K_(2)C_(2)O_(4)hArrAg_(2)C_(2)O_(4)+K_(2)CO_(3) Ar equilibrium the solution contains 0.0358 mole of K_(2)CO_(3) . Assuming degree of dissociation of K_(2)C_(2)O_(4) and K_(2)CO_(3) to be same, calculate K_(SP) of Ag_(2)CO_(3) .

An organic compound 'A' (C_(4)H_(10)O) is optically active. On mild oxidation, it gives a compound 'B' (C_(4)H_(8)O) but upon vigorous oxidation, it gives another compound 'C' (C_(3)H_(6)O_(2)) . The compound 'C' along with 'D' are also formed from 'B' by reacting with iodine in the presence of alkali. Deduce the structures of 'A', 'B', 'C' and 'D' .

The concentration of Ag^(o+) ions in a saturated solution of Ag_(2)C_(2)O_(4) is 2.0 xx 10^(-4)M . Calculate the solubility of Ag_(2)C_(2)O_(4) in a solution which is 0.01M in H_(2)C_(2)O_(4) .
