MOLECULAR POLARITYFIELD NOTE 140 / 175
Is NH2OH polar or nonpolar?
NH2OH is polar because its connected N and O centers have lone pairs and unequal bond directions.

Why NH2OH is polar
Nitrogen bonds to two hydrogens and oxygen and keeps a lone pair; oxygen bonds to nitrogen and hydrogen and keeps two lone pairs. These local pyramidal and bent environments create an asymmetric charge distribution.
What to notice
The written formula NH2OH is useful because it reveals the N–O bond. Treating all three H atoms as attached to N would be the wrong connectivity.
Common questions about NH2OH
- 01
What does the Lewis structure of NH2OH show?
The connectivity is H2N–O–H. N has one lone pair and O has two.
- 02
What is the molecular geometry of NH2OH?
NH2OH has a pyramidal at N; bent at O molecular geometry. The 3D model shows representative bond angles of 99.4° and 100.7° and 106.9°. These angles come from the displayed model coordinates.

What is the molar mass of NH2OH?
NH2OH has an approximate molar mass of 33.03 g/mol, calculated from its formula using abridged standard atomic weights. Natural isotope variation can change the last digits.
