How does methyl alcohol react with :
(i) Sodium (i) `PCl_(5)` (iii) Acetyl chloride (iv) `Na_(2)Cr_(2)O_(7)//H_(2)SO_(4)`

What happens when phenol is oxidized by Na_(2)Cr_(2)O_(7)//H_(2)SO_(4)?

Na_(2)CrO_(4)+HCl to H_(2)Cr_(2)O_(7)+Na_(2)SO_(4)

Na_(2)CrO_(4)+HCl to H_(2)Cr_(2)O_(7)+Na_(2)SO_(4)

The final product obtained in the oxidation of t-butyl benzene with Na_(2)Cr_(2)O_(7)+H_(2)SO_(4) is:

Sodium sulphite (Na_(2)SO_(3)) is added to meat as a preservative. The presence of Na_(2)SO_(4) can be detected by adding dil. H_(2)SO_(4) when the pungent smelling gas evolved turns the lime water milky. The gas evolved was detected as sulphur dioxide. The SO_(2) " to "SO_(4)^(2-) in titration. SO_(2)+2H_(2)O+I_(2) to 4H^(+)+SO_(4)^(2-)+2I^(-) In order to check the results of titration, excess barium chloride is added to the final solution. The resulting precipitate is collected and weighed. Q. SO_(2) and CO_(2) both lime water milky. Which of the following reagent can be used to distinguish these two gases? (I) K_(2)Cr_(2)O_(7)"/"H_(2)SO_(4) (II) KMnO_(4)"/"H^(+) (III) I_(2) solution

Among the following, the number of compounds that can react with PCl_(5) to give POCl_(3) is O_(2) , CO_(2) , SO_(2) , H_(2)O , H_(2)SO_(4) , P_(4)O_(10) .

Calculate the equivalent weight of following assuming molecular weight M (i) H_(3)BO_(3) (ii) H_(3)PO_(2) (iii) FeSO_(4).(NH_(4))_(2).6H_(2)O (iv) K_(2)SO_(4)Cr_(2)(SO_(4))_(3).24H_(2)O (v) Al_(2)O_(3) (vi) HNO_(3) (vii) MgCO_(3) (Viii) CaSO_(4)

How is methanol obtained from methyl bromide ? How would you convert methyl alcohol into (i) Formaldehyde (ii) Methyl chloride (iii) Sodium methoxide (iv) Methyl acetate ?

How do you prepare : (i) k_(2)MnO_(4) from MnO_(2) ? (ii) Na_(2)Cr_(2)O_(7) from NaCrO_(4) ?

Assertion : Solid potassium dichromate gives greenish yellow vapour with concentrated H_(2) SO_(4) and solid ammonium chloride. Reason : The reaction of ammonium chloride with solide K_(2) Cr_(2) O_(7) and concentrated H_(2) SO_(4) produces chromyl chloride.
