Phosphine has the following electronic structure. Structure of phosphine The electronic structure of phosphine is similar to ammonia in that it has a pyramidal structure. The bond angle H-P-H, however, is = 93 o (e.g., NH 3 =107 ..

Each eye is a spherical structure that comprises of a lens and a three-layered wall. ..

Electronic structure of carbon monoxide may be represented as follows:..

BeH 2 has a three-centre bond and is highly polymerised by means of BeHBe bond...

Organic cyanides has a triple bond between the C and N atoms i.e., one sigma and two pi bonds are present. Thus nitrogen here is sp hybridized. The C-C N bond angle is 180 o . Bond length of then the triple bond C N is shorter than the double bond C=N in imines and C - N single bond in amines. The ..

Respiratory System in Human Beings The respiratory system starts with the nose that encloses the nasal cavity. The nasal cavity opens to the outside through the openings called the nostrils. The nasal cavity is divided into two portions by a cartilagenous septum and is lined by fine hairs that..

Internal View of the Heart The human heart is four-chambered. The upper chambers are called the atria or the auricles and the lower two chambers are called the ventricles. The two atria are separated by the interatrial septum. The two ventricles are separated from each other by the interventricular..

The respiratory system starts with the nose that encloses the nasal cavity . The nasal cavity opens outside through the openings called the nostrils . The nasal cavity is divided into two portions by a cartilagenous septum and is lined by fine hairs that filter the dust particles from the air...

Structure of Proteins Primary Structure - Proteins are biopolymers containing a large number of amino acids joined to each other by peptide linkages having three dimensional structures. The structure of proteins is a complex one which is divided into 4 parts...
