How do you convert ethanal to propanone 2th chemistry answer?
Answers
Ethanal to Propanone
Well Method 1
Reaction of Ethanal with RMgX ( in this case we gonna take CH3MgCl) in the acidic medium to directly give CH3-CH(OH)-CH3
Oxidizing CH3-CH(OH)-CH3 with K2Cr2O7 to give Ketone as the only product and we have CH3—CO—CH3(propanone )
Incase you need another one ( Longer One) !
Reaction of Ethanal with Zn-Hg-HCl + ▲ to give out Ethane (CH3-CH3)[Clemmensen Reduction].
Reaction of Ethane with Cl2 in presence of sunlight to give CH3-CH2-Cl[Clemensen Reaction ]
Reaction of CH3-CH2-Cl with CH3-Cl in presence of dry ether and Na to give Propane (CH3-CH2-CH3) [Wurtz Reaction]
Reaction of of Propane with Cl2 in presence of sunlight to give CH3-CH2-CH2-Cl
Reaction of CH3-CH2-CH2-Cl with alc KOH to give CH3-CH=CH2
Reaction of H2O with H+ to give CH3-CH(OH)-CH3
Oxidizing CH3-CH(OH)-CH3 with K2Cr2O7 to give Ketone as the only product and we have CH3—CO—CH3(propanone )
2. Toluene to Benzoic acid
Method 1
Direct method : Reaction of KMnO4 in presence of KOH to give out Benzoic acid .
Method 2 ( a little bit longer )
Reaction Cl2 in presence of light which will produce C6H5CH2—Cl
Reaction of C6H5CH2—Cl with aqueous KOH forms C6H5CH2OH
Oxidizing the obtained compound in presence of KMnO4 it will form C6H5COOH
