For .. N H_2^- (the amide ion), the best three-dimensional view is

JEE Main Chemistry question

For (the amide ion), the best three-dimensional view is

(A)A bent (angular) geometry with the lone pair occupying one corner of a tetrahedral arrangement around N, both N–H bonds pointing below the lone pairCorrect
(B)A linear arrangement of H–N–H
(C)A symmetric pyramidal arrangement with the lone pair pointing straight up, away from both N–H bonds
(D)A trigonal planar arrangement of H, H and the lone pair in one plane

Answer: (A)

Solution

The ion has nitrogen as the central atom with 2 bond pairs (to the two H atoms) and 2 lone pairs, giving a steric number of 4 ( hybridisation, parent tetrahedral electron geometry). With 2 of the 4
