(a) Draw Lewis structures for :
(i) Ethanol `(C_2 H_5 O H)`
(ii) `BrNO`
(iii) `HOCN`
(iv) `NH_2 OH` (Kydroxylamine).
(b) Give an isomeric structure for `NH_2 OH` and explain which structure is more stable.

Explanation

(a) (i)
(b) Rearrange the structure of `NH_2 OH` as given in (iv) above with formal charges.
`underset((I))H-ddotunderset(H)underset(|)(N)-O-Hharrunderset((I))(H-underset(H)underset(|)overset(H)overset(|)N^(o+))-overset(ddotTheta)underset(..)O:`
In structure`(I), F.C.` on each atom is zero, whereas in structure `(II), F.C` on `N` and `O` is `+ 1` and `-1`, respectively. So, structure `(I)` is more stable since it has maximum number of atoms with normal convalencies with no formal charges.
