Propanal mein toh ek hi carbanion ban sakta hai na? Even I was thinking 4 at first...I didn't try by writing down.
Wait propanone mein bhi ek hi carbanion possible hai...lol symmetrically same both sides.
See, 2 carbanions means 4 products. A carbanion can react with its initial substrate or with another substrate.
Naming them will take a while...kaam karo, aldol condensation ke mechanism se karo. CH3CH-CHO and CH2-COCH3 are possible carbanions. Make each of them react by nucleophilic addition on propanal and propanone one by one. So 4 products will be possible. One carbanion can add to either propanal or propanone.
Fine Pritish Thx I'll try to get the products
Plzz confirm them whenever u r free
2 oxo hex3ene
2methyl4oxopen2ene
2,3dimethyl4oxobutane
1oxo2methylpent2ene
