Complete the reactions with appropriate products.(i) CH3CHO+NH2OH→X(ii) CH2=CH2+PdCl2+H2OCuCl2−−−−→Y(iii) CH3CH2CH2CH2OHCrO3−H2SO4−−−−−−−−→Z
X,Y and Z are three organic compounds. All the three undergo iodoform test .Only Y and Z can react with 2,4 -DNP. Only Z can reduce tollen's reagent. Here X,Y and Z respectively
Let x, y, z be positive reals. Which of the following implies x = y = z?
(I) x3 + y3 + z3 = 3xyz
(II) x3 + y2 z + yz2 = 3xyz
(III) x3 + y2 z + z2 x = 3xyz
(IV) (x + y + z)3 = 27xyz
