Explanation of Reactions in Carbanions I Worksheet:
In organic chemistry, carbanions are carbon atoms carrying a negative charge, making them highly reactive. The reactions in the Carbanions I Worksheet demonstrate the transformations possible with carbanions through nucleophilic addition and substitution reactions.
1. Reaction 1: 2-methyl-3-phenylpropanal + dilute NaOH This reaction involves the addition of a nucleophile (OH-) to 2-methyl-3-phenylpropanal, resulting in the formation of a carboxylic acid.
2. Reaction 2: Propiophenone + Ph3PCHCH3 Propiophenone reacts with the reagent Ph3PCHCH3 to form a new compound through nucleophilic attack on the carbonyl carbon.
3. Reaction 3: Methyl Benzoate + CH3CH2O18H1, H* This reaction involves ester hydrolysis of methyl benzoate using ethanol and water as nucleophiles, resulting in a carboxylic acid product.
4. Reaction 4: 2,2-dimethylpropanal + conc. NaOH Addition of a nucleophile (OH-) to 2,2-dimethylpropanal leads to the formation of a carboxylic acid.
5. Reaction 5: Propiophenone + dilute NaOH Similar to Reaction 1, this reaction forms a carboxylic acid by adding a nucleophile (OH-) to propiophenone.
6. Reaction 6: Cyelohexanone + 2-methyl-3-phenylpropanal + dilute NaOH Cyelohexanone and 2-methyl-3-phenylpropanal react with dilute NaOH to form two carboxylic acids through nucleophilic attack.
7. Reaction 7: 3-methyl-2-butanone + Br, OH- Nucleophilic substitution occurs in 3-methyl-2-butanone, replacing the bromine atom with OH- to form a new compound.
These reactions highlight the reactivity of carbanions and their involvement in various chemical transformations in organic chemistry.
