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

A

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
A
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., II gt III gt I gt IV`.
