Which of the following compound give methane on treatment with CH3MgI ...
Compound that gives methane on treatment with CH3MgI:
- The compound that gives methane on treatment with CH3MgI is PhCHO (Benzaldehyde).
Order of leaving ability:
1. CH3-C-CH2-C (Least leaving ability)
2. PhCHO (Benzaldehyde)
3. CH3 (Most leaving ability)
Explanation:
- The order of leaving ability is determined by the stability of the resulting carbanion after the leaving group is removed.
- In this case, when CH3MgI reacts with the given compounds, it forms a carbanion intermediate.
- The stability of the carbanion depends on the electron-donating or withdrawing groups attached to the carbon.
- In the given compounds, the carbanion stability is highest in the case of CH3 due to hyperconjugation and electron donation by methyl group.
- Benzaldehyde (PhCHO) is more stable than CH3-C-CH2-C due to the delocalization of the negative charge into the aromatic ring.
- CH3-C-CH2-C has the least stability as the carbanion is formed on a sp3 hybridized carbon, which is less stable compared to sp2 hybridized carbon in benzaldehyde.
- Therefore, the correct order of leaving ability is CH3 (Most leaving ability) > PhCHO (Benzaldehyde) > CH3-C-CH2-C (Least leaving ability).
- The compound that gives methane on treatment with CH3MgI is PhCHO (Benzaldehyde).
Order of leaving ability:
1. CH3-C-CH2-C (Least leaving ability)
2. PhCHO (Benzaldehyde)
3. CH3 (Most leaving ability)
Explanation:
- The order of leaving ability is determined by the stability of the resulting carbanion after the leaving group is removed.
- In this case, when CH3MgI reacts with the given compounds, it forms a carbanion intermediate.
- The stability of the carbanion depends on the electron-donating or withdrawing groups attached to the carbon.
- In the given compounds, the carbanion stability is highest in the case of CH3 due to hyperconjugation and electron donation by methyl group.
- Benzaldehyde (PhCHO) is more stable than CH3-C-CH2-C due to the delocalization of the negative charge into the aromatic ring.
- CH3-C-CH2-C has the least stability as the carbanion is formed on a sp3 hybridized carbon, which is less stable compared to sp2 hybridized carbon in benzaldehyde.
- Therefore, the correct order of leaving ability is CH3 (Most leaving ability) > PhCHO (Benzaldehyde) > CH3-C-CH2-C (Least leaving ability).
