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.IIgtIIIgtIgtIV,):}`
