The organic compounds three structural representation is explained below: entire structure, condensed structure, and bond line structural formulas. Legal. status page at https://status.libretexts.org. In the molecular formula, a compound is represented by counting up all of the different types of atoms and listing themin order. In the case of butane, its two isomers will have these structural formulas Notice that isobutane has a propane parent chain with a methyl group - CH 3 attached to the second carbon of the chain - that is why its IUPAC name is 2 2. Sol: Step 1: All hydrogen atoms bonded directly to the carbon atom are removed. Using this formula, we can write a molecular formula for any alkane with a given number of carbon atoms. Heteroatoms(any other atom than carbonor hydrogen) and hydrogens attached toheteroatoms are shown in condensed form.

The ultimate condensed formula is the skeletal formula (sometimes known as a line-angle formula), in which carbon atoms are implied at the corners and ends of lines, and each carbon atom is understood to be attached to enough hydrogen atoms to They simplyprovide the numbers of eachtype of atom present in the molecule, but they carry no information about how the atoms are joined together in space.For example, the molecular formula \({{\rm{C}}_{\rm{4}}}{{\rm{H}}_{{\rm{10}}}}\) tells us there are four carbon atoms and ten hydrogen atoms in a molecule. Write the condensed structural formulas and name for all the constitutional isomers with the formula C Condensed structural chemical formulas show the hydrogen atoms (or other atoms or groups) right next to the carbon atoms to which they are attached. Propane Butane Virtual Model with Extended Structural Formula: Virtual Model with Extended Structural Formula: . I-0-3 Condensed Structural Formula: IC!

Dots \(\left( {\rm{ \bullet }} \right)\) are used to represent electrons, and. The organic compounds three structural representation is explained below: entire structure, condensed structure, and bond line structural formulas. Legal. status page at https://status.libretexts.org. In the molecular formula, a compound is represented by counting up all of the different types of atoms and listing themin order. In the case of butane, its two isomers will have these structural formulas Notice that isobutane has a propane parent chain with a methyl group - CH 3 attached to the second carbon of the chain - that is why its IUPAC name is 2 2. Sol: Step 1: All hydrogen atoms bonded directly to the carbon atom are removed. Using this formula, we can write a molecular formula for any alkane with a given number of carbon atoms. Heteroatoms(any other atom than carbonor hydrogen) and hydrogens attached toheteroatoms are shown in condensed form. Write condensed structural formulas for alkanes given complete structural formulas. WebQuestion: What is the condensed structural formula for the following: propane, butane, isobutane, Isopentane, ethylene, ethyne, cyclohexene, benzene, propyne and ethane?

Halogen atoms count for one hydrogen; for nitrogen atoms, substract NH from the formula before assessing unsaturation; i.e. However, the molecular formulaedo not provide adequate information for chemical analysis. 2-hydroxy-2-methylpropanal Chemists often use condensed structural formulas to alleviate these problems. 
3. Such a formula does not directly tell how the For example . Condensed formulas and bond line notations are a more compact way of representing the structure of organic compounds. The connectivity of each atom, bond, and lone paircan be explained through the complete structural formula. The condensed formulas show hydrogen atoms right next to the carbon atoms to which they are attached, as illustrated for butane: Even more abbreviated is a line-angle formula, also called a skeletal structure, in which carbon atoms are implied at the corners and ends of lines, and each carbon atom is understood to be attached to enough hydrogen atoms to give each carbon atom four bonds.
