Comparison Between Single, Double and Triple Covalent Bonds
Single, double and triple covalent bonds differ from each other in the following ways. Single bond is formed by the sharing of one electron pair, (two electrons); a double bond is formed by the sharing of two electron pairs, (four electrons), wherea..
Bond length
Bond length is the average distance between the centres of the nuclei of two bonded atoms in a molecule. It is expressed in Angstrom units () or picometers(pm). 1 = 10 - 1 0 m and 1pm = 10 - 1 2 m. It is determined with the help of X-rays diffraction and other sp..
Double Covalent Bond
A double covalent bond consists of two pairs of shared electrons. It is formed by the sharing of two pairs of electrons between two atoms. It is actually a combination of two single bonds. It is represented by putting two short lines between the two atoms [=]. Let us t..

Formation of Molecules having Double Bond
Formation of oxygen (O 2 )Molecule - Each oxygen atom has six electrons in its valence shell. Thus, it requires 2 more electrons to achieve the nearest noble gas configuration. This is achieved by sharing two pairs of electrons by the two oxygen atoms as shown belo..

Bond Order
The relative stability of a molecule can be determined on the basis of bond order. It is defined as the number of covalent bonds in a molecule. It is equal to one half of the difference between the number of electrons in the bonding and antibonding molecular orbital..

In molecules containing double bond, which has a pi bond, there is no free rotation and such molecules exist in isomeric forms of 'cis' and 'trans'. In the 'cis' form the similar atoms lie on the same side of a plane placed along the internuclear axis while in the 't..

She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Very good, Tutor was clear and guided me through the whole algebra problems
It is at a nice pace to shoot down all my problems I was having on my assignment. excellent tutoring at affordable cost ...Really amazing,Thank you
