The Lewis structure for CH3Br has the carbon in the center with four electrons around it and the three hydrogens and bromine each sharing a single electron with the carbon. The bromine has an additional three pairs of electrons surrounding it.Continue Reading
Lewis structures show how atoms bond to each other to form a complete molecule, and they are useful for demonstrating bonding in basic molecules, such as bromomethane. In some cases, lines are used to indicate bonds, but dots are more common when dealing with basic compounds. In addition to bonding electrons, these diagrams also show nonbonding electrons, such as in the case of bromine in bromomethane. Bromine, in this instance, has three pairs of electrons that are not actively involved in the bonding between it and carbon.
In general, Lewis structures demonstrate that most atoms, with the exception of hydrogen, form molecules to get a total of eight electrons in their outer shells. However, these structures can also be used to hint at the overall shape of a molecule. In the case of bromomethane, the four atoms around the carbon must be arranged fairly evenly in a 3D space, so they form a tetrahedral structure. However, because bromine forms such a long (and therefore weaker) bond, the hydrogens have a little more space than in methane, resulting in a slightly distorted tetrahedral.Learn more about Atoms & Molecules
The Lewis dot structure for CH3CN, the formula for acetonitrile, is drawn with a C (carbon) in the center with four radiating lines, three of which connect to H (hydrogen) and one of which connects to another C. The second C is connected by three straight lines to an N (nitrogen), which has two dots around it.Full Answer >
The Lewis structure of HCOOH places the carbon atom at the center, surrounded by a single bond to a carbon and an oxygen atom, with a double bond to the remaining oxygen group. The single-bonded oxygen has a single bond to a hydrogen atom. There are an additional four electrons around each oxygen atom to account for those not used in bonding and to satisfy the octet rule for oxygen.Full Answer >
The Lewis structure of C2Cl4 includes a double-bonded, two-carbon chain with two chlorine atoms attached to each carbon atom. At each end, the chlorine atoms are spaced approximately 120 degrees from each other and from the carbon atom.Full Answer >
The Lewis structure for Cl3PO is a diagram used in chemistry to graphically represent chemical bonding of phosphorous, chlorine and oxygen. In the diagram, phosphorous is in the center because it has the least tendency to draw electrons toward it.Full Answer >
