3-dimensional (3D) chemical structure image of 1-BUTYNE

The 2D chemical structure image of 1-BUTYNE is also called skeletal formula, which is the standard notation for organic molecules. The carbon atoms in the chemical structure of 1-BUTYNE are implied to be located at the corner(s) and hydrogen atoms attached to carbon atoms are not indicated – each carbon atom is considered to be associated with enough hydrogen atoms to provide the carbon atom with four bonds.

The 3D chemical structure image of 1-BUTYNE is based on the ball-and-stick model which displays both the three-dimensional position of the atoms and the bonds between them. The radius of the spheres is therefore smaller than the rod lengths in order to provide a clearer view of the atoms and bonds throughout the chemical structure model of 1-BUTYNE.
