# What are the 4 types of bonds carbon can form?

## What are the 4 types of bonds carbon can form?

Carbon can form single bonds (sharing of 2 electrons), double bonds (sharing of 4 electrons), and/or a triple bond (sharing of 6 electrons).

What is the molecular geometry of a molecule with 4 groups attached to the central atom?

# of bonding groups/domains on ‘central’ atom # of lone pair electrons on ‘central’ atom Molecular Geometry
4 0 tetrahedral
3 1 trigonal pyramidal
2 2 bent
5 0 trigonal bipyramidal

### What is the basic geometry of a central atom with 4 electron groups?

4 electron pairs around a central atom adopt tetrahedral geometry.

What is the correct EPG for a central atom with 4 bonds?

tetrahedral
A central atom with 4 bonds has a MG = tetrahedral and an EPG = tetrahedral. When there are 3 bonds and one lone pair as in ammonia (NH3), the structure has a MG = trigonal pyramid while retaining the EPG = tetrahedral.

#### What are the groups around the central atom called?

Each group around the central atom is designated as a bonding pair (BP) or lone (nonbonding) pair (LP). From the BP and LP interactions we can predict both the relative positions of the atoms and the angles between the bonds, called the bond angles.

What makes a carbon atom a substituent of a molecule?

According to the above rules, a carbon atom in a molecule, considered as a substituent, has the following names depending on the number of hydrogens bound to it, and the type of bonds formed with the remainder of the molecule:

## What kind of molecule has lone pair on central atom?

Recall that the trigonal bipyramidal geometry has three equatorial atoms and two axial atoms attached to the central atom. Because of the greater repulsion of a lone pair, it is one of the equatorial atoms that are replaced by a lone pair. The geometry of the molecule is called a distorted tetrahedron, or seesaw.

Where does the term substituent come from in chemistry?

(In organic chemistry and biochemistry, the terms substituent and functional group, as well as side chain and pendant group, are used almost interchangeably to describe those branches from the parent structure, though certain distinctions are made in polymer chemistry. In polymers, side chains extend from the backbone structure.
