Show the polarisation of the carbon-magnesium bond in the following structure: $CH_3-CH_2-CH_2-CH_2-MgX$.
(N/A) The electronegativity of $Mg$ $(1.2)$ is significantly lower than that of $C$ $(2.5)$.
Consequently,the $Mg$ atom acquires a partial positive charge $(\delta^+)$,and the carbon atom directly attached to it acquires a partial negative charge $(\delta^-)$.
The polarized bond is represented as: $CH_3-CH_2-CH_2-CH_2^{\delta-}-Mg^{\delta+}X$.
Consequently,the $Mg$ atom acquires a partial positive charge $(\delta^+)$,and the carbon atom directly attached to it acquires a partial negative charge $(\delta^-)$.
The polarized bond is represented as: $CH_3-CH_2-CH_2-CH_2^{\delta-}-Mg^{\delta+}X$.
