How will you synthesise 2-butanone from ethyl alcohol ?
Clue : Steps are (i) `SOCl_(2)` (ii) `Mg//"ether"` (iii) `CH_(3)CHO`, (iv) `H_(2)O //H^(+)` and (v) `Na_(2)Cr_(2)O_(7) // H_(2)SO_(4)`.

Aniline on oxidation with Na_(2)Cr_(2)O_(7) and H_(2)SO_(4) gives :

Acidifed K_(2)Cr_(2)O_(7) oxidises H_(2)S to :

Calculate the molar mass of the following: (i) H_(2)O , (ii) CO_(2) , (iii) CH_(4)

Calculate the molecular mass of (i) oxalic and (ii) Formic acid (iii) H_(2)SO_(4) (iv) FAS, (v) Na_(2)CO_(3) (vi) sucrose

When KCl is heated with conc. H_(2)SO_(4) and solid K_(2)Cr_(2)O_(7), we get

How would you name the following compounds ? (i) CH_(3)-CH_(2)-Br (ii) H-overset(H)overset(|)C=O (iii) CH_(3)-CH_(2)-CH_(2)-CH_(2)-C -= CH_(2)

Complete the following equations. (i) MnO_(2)+KOH+O_(2)to . (ii) Na_(2)Cr_(2)O_(7)+HCl to .

Complete the following: CH_(3)-CH=CH_(2)+H_(2)O to .

Complete the following equations i) CH_(4)+2O_(2)rarr ii) 2Fe^(3+)+SO_(2)+2H_(2)Orarr iii) C_(12)H_(22)O_(11)+H_(2)SO_(4)" (conc)"rarr

A posible mechanism for the reaction : 2NO + 2H_(2) to N _(2) + 2H_(2) O is : (i) 2NO + overset(k _(1))hArr N _(2) O _(2) (ii) N _(2) O _(2) + H _(2) overset(k _(2))to N _(2) O + H _(2) O (iii) N _(2)O + H _(2) overset(k _(3)) to N _(2) + H _(2)O If the second step is the rate determining step then rate law may be written as : ?
