When ethyl alcohol is oxidised by acidified potassium dichromate,

C H_{3} COO H (Y)

is obtained as :

X 3 C_{2} H_{5} O H + 2 K_{2} C r_{2} O_{7} + 8 H_{2} S O_{4} ⟶

Y 3 C H_{3} COO H + 2 C r_{2} (S O_{4})_{3} + 2 K_{2} S O_{4} + 11 H_{2} O

Carboxylic acid undergo reduction with

L i A l H_{4}

to give primary alcohol as

(Y) C H_{3} - C ∣∣ O - O H L i A l H_{4} (Ether) (X) C H_{3} C H_{2} O H

S o, X

is

C H_{3} C H_{2} O H

and

Y

is

C H_{3} COO H

Q. When compound $X$ is oxidised by acidified potassium dichromate, compound $Y$ is formed. Compound $Y$ on reduction with $L i A l H_{4}$ gives $X . X$ and $Y$ respectively are :

$C_{2} H_{5} O H, C H_{3} COO H$

$C H_{3} COC H_{3}, C H_{3} COO H$

$C_{2} H_{5} O H, C H_{3} COC H_{3}$

$C H_{3} C H O, C H_{3} COC H_{3}$

Q. When compound X is oxidised by acidified potassium dichromate, compound Y is formed. Compound Y on reduction with LiAlH4​ gives X.X and Y respectively are :

C2​H5​OH,CH3​COOH

CH3​COCH3​,CH3​COOH

C2​H5​OH,CH3​COCH3​

CH3​CHO,CH3​COCH3​

Q. When compound $X$ is oxidised by acidified potassium dichromate, compound $Y$ is formed. Compound $Y$ on reduction with $L i A l H_{4}$ gives $X . X$ and $Y$ respectively are :

$C_{2} H_{5} O H, C H_{3} COO H$

$C H_{3} COC H_{3}, C H_{3} COO H$

$C_{2} H_{5} O H, C H_{3} COC H_{3}$

$C H_{3} C H O, C H_{3} COC H_{3}$
