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 ion

What is a chemical bond ?

Chemical bond may be defined as the force of attraction by which two atoms are held together. The chemical bonds lead to the formation of molecules and crystals. There are various kind of bonding that we see around us. Covalent bond A covalent bond is formed by mutual sharing of electrons between two atoms. For

What is the difference between stereoisomers, optical isomers and enantiomers?

Stereoisomers:- these are the compounds that have same molecular formula but different arrangement of atoms in the space. Optical isomers:- the compunds that have same molecular formula but they rotate the plane polarised light to the different side, right side-dextrorotatory and left levorotatory. Enantiomer:- these are the compounds that are mirror images of each other

How to find a lone pair in simple way?

Step 1: write the configuration of element and then show the valence elactrons around the symbol of element . Step2: make the bonds around the atom according to its valency and use the electrons for making the bonds. Step3: Now see if there are any unshared electrons pairs. These are your lone pairs. See the
