प्रश्न
In which of the following compounds the carbon marked with asterisk is expected to have greatest positive charge?
विकल्प
*CH3 – CH2 – Cl
*CH3 – CH2 – Mg+ Cl–
*CH3 – CH2 – Br
*CH3 – CH2 – CH3
उत्तर
*CH3 – CH2 – Cl
Explanation:
Order of electronegativity of the attached group is as follows:
Cl > Br > C > Mg.
More electronegative group attached to the C will give more positive charge. Therefore, in case asterisk C will have greatest positive charge.
