ammonia chemical structure

3 ) Ammonia molecule has an electronegative nitrogen atom bonded to three hydrogen atoms. Differences in electronegativity between nitrogen and hydrogen makes each hydrogen atom acquires positive charge. Thus, in the molecule, there is one negative site and three positive..

In a molecule of ammonia, nitrogen, an electronegative atom is bonded to three hydrogen atoms. The nitrogen atom forms a negative site of the molecule whereas each of three H-atoms acquires a partial positive charge. The ammonia molecules are associated by H-bonds as shown belo..

Ammonia was known to mankind since a long period, as it was produced in nature by putrefying and ammonifying bacteria. Chemical compound, NH 3 colorless gas that is about one half as dense as air at ordinary temperatures and pressures. It has a characteristic..

. In ammonia, the basic nature is attributed to the lone pair. In water the oxygen atoms has 2 lone pair of electrons. These account for water being a universal solven..

Reducing Action - Ammonia acts as a reducing agen..

Combustibility - Ammonia is neither combustible in air nor does it support combustion. However it burns in oxygen with a greenish-yellowish flame producing water and nitroge..

All these hydrides are covalent in nature and have pyramidal structure. These involve sp 3 hybridization of the central atom and one of the tetrahedral position is occupied by a lone pair. Shape of NH 3 molecule Due to the presence of lone pair, the bo..

Structurally all types of chlorophyll resemble one another. All of them contain four pyrrole rings [also called porphyrin] which are linked together by methane bridges (-CH=). The skeleton of each pyrrole ring is made up of five atoms - four carbon and one nitrogen with magnesium in the c..
