Question

carry out the conversion: propanoic acid to acetic acid​

Answer 1

: propanoic acid to acetic acid​

Answer 2

First add Na to propanoic acid:

CH3CH2COOH+NaOH= CH3CH2COONa+H2O

Now add NaOH again in presence of CaO to CH3CH2COONa:

CH3CH2COONa+NaOH(CaO)= C2H6+Na2CO3

Now oxidize the C2H6 with K2Cr2O7:

C2H6+K2Cr2O7= CH3COOH

Hope this helped!
