Vedclass · Answer

(D) Magnesium $(Mg)$ belongs to Group $2$ (alkaline earth metals). $1$. Sodium $(Na)$ is in Group $1$ and is more electropositive than $Mg$. $2$. Electrolysis of aqueous $MgCl_2$ produces $H_2$ gas at the cathode instead of $Mg$ because $H^+$ ions are reduced more easily than $Mg^{2+}$ ions. $Mg$ is obtained by the electrolysis of fused (molten) $MgCl_2$. $3$. $Mg$ is a reducing agent,but not as strong as alkali metals like $Na$. $4$. Magnesium shows a diagonal relationship with Lithium $(Li)$,not Boron $(B)$. Wait,re-evaluating the options: The question asks for the true statement. Upon review,none of the provided options are strictly correct based on standard chemistry. However,if we must choose the most chemically relevant concept often tested,the diagonal relationship is between $Mg$ and $Li$. Given the constraints,if this is a multiple-choice question where one must be selected,there might be an error in the question source. Assuming the intended answer is related to the diagonal relationship (even if the element is incorrect),or if the question implies a specific context,$I$ will mark the most plausible intended answer if applicable. Since all are factually incorrect,$I$ will flag this as an error.
