Question
What is the correct order of electronegativity ?
A.
$${M^ - } < {M^{2 - }} < {M^{3 - }} < {M^{4 - }}$$
B.
$${M^ - } > {M^{2 - }} > {M^{3 - }} > {M^{4 - }}$$
C.
$${M^ - } < {M^{2 - }} > {M^{3 - }} < {M^{4 - }}$$
D.
$${M^{4 - }} < {M^{2 - }} < {M^{3 - }} < {M^ - }$$
Answer :
$${M^ - } > {M^{2 - }} > {M^{3 - }} > {M^{4 - }}$$
Solution :
Higher the positive charge the greater is the $$EN$$ and higher the negative charge the lesser is the $$EN.$$ So, $$EN$$ order is
$${M^ - } > {M^{2 - }} > {M^{3 - }} > {M^{4 - }}$$
