Question:
Show the polarisation of carbon-magnesium bond in the following structure.
CH3—CH2—CH2—CH2—Mg—X
Solution:
CH3—CH2—CH2—δ-CH2—δ+Mg+ X-
Carbon is more electronegative than Mg because of the electronegativity difference in the bond between C-Mg is highly polarised. C being more electronegative the electron density is towards C hence Mg readily loses its electron to form C-( carbanion).
