The correct order of decreasing electronegativity values among the elements I-beryllium, II-oxygen, III-nitrogen and IV-magnesium is

Answer»

`(II)gt(III)gt(I)gt(IV)`
`(III)gt(IV)gt(II)gt(I)`
`(I)gt(II)gt(III)gt(IV)`
`(I)gt(II)gt(IV)gt(III)`

SOLUTION :ELECTRONEGATIVITY VALUES of given elements are as follows:
`{:(Be-1.5(I),Mg-1.2(IV)),(O-3.5(II),N-3.0(III)),(i.e.IIgtIIIgtIgtIV,):}`
