tetrahedral
Chat with our AI personalities
The electron pair geometry of each carbon atom in an alkane is tetrahedral. This is because each carbon atom is bonded to four other atoms, which results in a geometry where the electron pairs are distributed in a tetrahedral arrangement around the carbon atom.
A carbon atom in an alkane forms a total of four bonds, typically with four hydrogen atoms. This allows the carbon atom to achieve a stable electron configuration with eight electrons in its outer shell.
halo alkane or alkyl halides
The electron geometry is tetrahedral when there are 4 electron groups around the central atom. This means the electron groups are arranged in a 3D shape resembling a pyramid with a triangular base.
Each carbon atom has sp2 hybridization and are locked in the same plane due to the double bond located between them. The carbon atoms have 3 electron groups surrounding them with no lone pairs present thefore, It will have a trigonal planar geometry
three dimensional arrangement of atoms electron-group geometry
