non-bonding electron pair
The unbound/unshared pair which remain about the atom.
Atom covalently bonded to one or more atoms in a molecule. The electrons on the central atom determine the shape of the molecule.
of or in or along or relating to a line
an arrangement of atoms in the VSEPR model where the three pairs of electrons are placed 120 degrees apart on a flat plane.
a structural arrangement in which four particles surrounding a central particle are orientes toward the corners of a four sided pyramid
four bonds, three of which make a pyramidal structure
hydrocarbon containing only single covalent bonds
the repulsion between electron pairs causes molecular shapes to adjust so that the valence-electron pairs stay as far apart as possible
a hydrocarbon that contains a carbon-carbon double bond
a hydrocarbon containing one or more carbon-carbon triple bonds
an organic compound containing only carbon and hydrogen
any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon
a long molecule consisting of many similar or identical building blocks linked by covalent bonds
carboxylic functional group
a functional group consisting of a carbonyl group attached to a hydroxyl group ; it is found in carboxylic acids
alcohol functional group
hydroxyl group ( --OH)
a molecule that has two poles, or regions with opposite charges
A measure of the degree of inequality in the sharing of electrons between two atoms in a chemical bond.
the uneven distribution of molecular charge
law of electrostatics stating that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them
attractive forces in which a hydrogen covalently bonded to a very electronegative atom is also weakly bonded to an unshared electron pair of another electronegative atom
