How are covalent bonds and atoms related?

We can look upon this aspect in two different ways. 1. About individual atom if we consider the role of single atom in bonding , Maximum electron gain or loss is 3 electrons, so if an atom has more than 3 electrons it can not donate or gain electrons thus it follow covalent path byContinue reading “How are covalent bonds and atoms related?”

Why is carbon important for forming complicated molecules? Or why carbon makes a large number of molecules ?

The answer to this question is very simple . There are two major reasons behind it. 1. Catenation :- It is the property by which the carbon can make long chains, branched chains and ring or cylic structural by joining with its own atoms. Due to this it can make a variety of molecules. 2.Continue reading “Why is carbon important for forming complicated molecules? Or why carbon makes a large number of molecules ?”

Why sigma bond is stronger than pi bond?

Actually the sigma bond involves head to head overlapping of orbitals, due to which the overlapping takes place on a larger extent. That makes the bond more stronger as compared to pie bond. In pie bond there is a sidewise overlapping of orbitals which leads to lesser extent of overlapping and thus the bond formedContinue reading “Why sigma bond is stronger than pi bond?”

What are the chemical properties of Carboxylic Acids ?

Why is breaking of C-H bond given more preference over C-C bond though the bond energy of the latter is less than the first one?

In case of hydrocarbons , the c-c bond is normally safe due to following two reasons :- Difference between the electronegativity of Carbon and Hydrogen. Due to this reason the electrons of the shared pair stays closer to the C-atom which makes it easy to break the C-H bond and release hydrogen as hydronium ionContinue reading “Why is breaking of C-H bond given more preference over C-C bond though the bond energy of the latter is less than the first one?”

What is a Covalent bond ? / how a covalent bond is formed ?

This is the bond formed by mutual sharing of electrons between two atoms. The sharing between two atoms allow each atom to have a noble gas like a configuration. Single Double,triple ,covalent bonds. Single Covalent bond This kind of bond is formed by sharing of only one pair of electrons between the two atoms likeContinue reading “What is a Covalent bond ? / how a covalent bond is formed ?”

Why is an ionic bond not double or triple like a covalent bond?

To understand this we have to go in depth , that how the ionic bond is formed? Ionic bond is a bond basically formed due to strong electrostatic forces of attraction which is totally different from the covalent bond. Ionic bond is formed between atoms with very different  ionisation energy and electron affinity. This situationContinue reading “Why is an ionic bond not double or triple like a covalent bond?”

Bond angles of PF3 and PCl3

In case of PF3 the size of F is small and thus it approaches near to the central atom that is P. as it approaches near to P there comes the repulsion between the bond pairs, which widens the bond angle and makes it larger than in case of PCl3. Here two types of forcesContinue reading “Bond angles of PF3 and PCl3”

Covalent bonds versus ionic bonds.

There are two types of bonds that can be formed Either by sharing of electrons , that is covalent bond. Or 2. By transfer of electrons , that is ionic bond. Now the question is that , why to go for covalent bond? An important aspect of ionic bond is that the difference of electronegativityContinue reading “Covalent bonds versus ionic bonds.”

Why is a Cl-Cl bond stronger than an F-F bond?

This is due to the following two major reasons :- The fluorine atoms are very small in size . The florine element is having the highest electronegativity. Due to these two reasons the florine atoms are so near after the F-F bonding that the start repelling each other due to higher electron desity, which makesContinue reading “Why is a Cl-Cl bond stronger than an F-F bond?”

What causes Ionic bonds to form? Use NaCl (table salt) as an example to explain the formation of ionic bonds.

it is a very common question and common example too. i would love to answer. Most people say it is the bond formed due to the transfer of electrons, but this explanstion is not complete. Ionic bond is the bond formed due to strong electrostatic forces of attraction between two oppositely charged ions. here isContinue reading “What causes Ionic bonds to form?
