In methane, the valency of carbon is:
Methane has its molecular formula CH4.
It is formed by one carbon atom and four hydrogen atoms.
Hydrogen has its valency 1 and carbon being tetravalent needs four valence electrons to acquire noble gas configuration, where it shares its 4 electrons with four hydrogen atoms.
Therefore, the valency of carbon atom in Methane (CH4) is 4.
The bond which is formed by sharing of an electron pair between two atoms is known as:
Covalent bonds are formed by sharing of electrons.
Which of the following is a non-polar molecule?
When 2 molecules of different electronegativity are bonded together covalently the bonding electron cloud is more attracted towards atom with higher electronegativity. So, the bond between 2 Oxygen atom is non-polar . Since, it is the only bonding in oxygen molecule Oxygen molecule is non-polar.
Most of covalent compounds are found in
Compounds having lesser number of carbon atoms are gases like CH4, C4H10 and some are liquids. Compounds having greater number of carbon atoms are solids.
Shared electron pair in covalent compound AB will be drawn:
Because the shared pair of electrons always stays in between two elements.
