The shape of amines is

tetrahedral

trigonal pyramidal

trigonal bipyramidal

square pyramidal

Text Solution

Verified by Experts

The correct Answer is:

Like ammonia , nitrogen atom of amines is trivalent and carries an unshared pair of eletrons Thus nitrogen orbitals in amines are `sp^(3)` hybridised and the geometry is tetrahedral but the shape is trigonal pyramidal Due to the presence of unshared pair of electrons , the angle `C-N-E` (wher `E` C or H) is less than `1095^(@)` for instance it is `108^(@)` in case of trimethylamine .
