What is the Lewis structure with correct geometry of CH4?
tetrahedral
If these are all bond pairs the molecular geometry is tetrahedral (e.g. CH4). If there is one lone pair of electrons and three bond pairs the resulting molecular geometry is trigonal pyramidal (e.g. NH3). If there are two bond pairs and two lone pairs of electrons the molecular geometry is angular or bent (e.g. H2O).
How do you write the structure of methane?
Methane is a simplest of the saturated hydrocarbons with a chemical formula CH4. It consists of four hydrogen atoms and one carbon atom and is the simplest alkane. When natural methane reaches the surface of the atmosphere is called atmospheric methane and can be found under the seafloor as well as below the ground.
What is the shape of methane?
tetrahedron
Methane, for example, has the shape of a regular tetrahedron with carbon at the centre and a hydrogen atom at each corner. Each H―C―H angle in methane is 109.5°, and each C―H bond distance is 1.09 angstroms (Å; 1Å = 1 × 10−10 metre).
What is the bond angle of CH4?
It turns out that methane is tetrahedral, with 4 equal bond angles of 109.5° and 4 equal bond lengths, and no dipole moment. This brings up two questions.
What is the Lewis dot symbol of CH4?

What is the shape of methane CH4?
It turns out that methane is tetrahedral, with 4 equal bond angles of 109.5° and 4 equal bond lengths, and no dipole moment.
What is the bond structure of CH4?
Covalent bonds form as valence electrons are shared between two atoms. Lewis Structures and structural formulas are common ways of showing the covalent bonding in organic molecules. Formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
What is CH4 structure?
The Lewis structure of the methane (CH4) molecule is drawn with four single shared covalent bonds between the carbon and hydrogen atoms each. Moreover, as there exist sigma bonds only and one 2s and three 2p orbitals of the carbon produce four new hybrid orbitals, the hybridization of CH4 is sp3.
How is methane tetrahedral?
Methane is an example of tetrahedral electron pair geometry . The carbon has 4 valence electrons and needs 4 more electrons from four hydrogen atoms to complete its octet. The hydrogen atoms are as far apart as possible at 109 degree bond angles. The molecule is three dimensional.
