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. Chemists often use condensed structural formulas to alleviate these problems. For example, we can represent pentane (CH3CH2CH2CH2CH3) and isopentane [(CH3)2CHCH2CH3] as follows: Parentheses in condensed structural formulas indicate that the enclosed grouping of atoms is attached to the adjacent carbon atom. -: ] 1 iNV20=#= D:" R|`bWG7jf4a`NyoBDQ{668cL&Yp&7S P2G5OUH1u!d.ZS&;vN!$GpA8 V-O7F$C+uXjiS^\H878x@XF _e)K0d)# }nJ*G1n4p]j.Ga})@m\tZ2t9A(W5t| Gb|]ND:r+$6uRqC 1iw0:46}B Draw a line-angle structure for the compound CH3CH2CH(CH3)CH2CH2CH3.

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 On the left is shown the complete Lewis structure, showing all atoms and valence electrons. Give the condensedformula for the compound represented by this line-angle structure: 4. }}\), Study Carbon and Its Compounds Concept Here. Step 3: On removing carbon atoms, the skeletal structure looks like a straight line; hence, the straight line is drawn in a zig-zag manner so that the corners are apparent. Isopentane is commonly used in conjunction with liquid nitrogen to achieve a liquid bath temperature of 160 C. Each carbon atom is understood to be attached to enough hydrogen atoms to give each carbon atom four bonds. Amolecular formulais the simplest way to represent a compound. They thus represent distinct molecules with different properties. For example, the molecular formula C4H10 tells us there are 4 carbon atoms and 10 hydrogen atoms in a molecule, but it doesnt distinguish between butane and isobutane. ChemicalBook:CB3429086, eMolecules:5756850, MolPort 4-ethyloctane 3-ethyl-2 A condensed structural formula is a more compact way of representing the structural formula of a molecule.
