Q.3. Webextended structural formula and condensed structural formula for propane, Butane, isobutane, Isopentane, ethylene, ethyne, cyclohexene, Benzene, propyne and ethylbenzene This problem has been solved! 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
In Bond Line Structural Formula: 1. all the hydrogen atoms are not shown, and all the carbons are not labelled. Amolecular formulais the simplest way to represent a compound. They thus represent distinct molecules with different properties.
Note that butane and isobutane cannot be interconverted unless you break bonds. 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. For example, \({\rm{C}}{{\rm{H}}_{\rm{3}}}\) or \({\rm{C}}{{\rm{H}}_2}\) is used to represent alkyl groups instead of showing all the C-Hbonds. You'll get a detailed solution from a subject matter expert
Because the carbons on the left are drawn straight across, we cannot see corners easily, so bend your lines (zig-zag) so that the corners are apparent. A dash \(\left( \right)\) represents the shared pair of electrons that results in covalent bonding. InChI=1S/C6H14/c1-4-5-6(2)3/h6H,4-5H2,1-3H3, Except where otherwise noted, data are given for materials in their, National Institute for Occupational Safety and Health, https://en.wikipedia.org/w/index.php?title=2-Methylpentane&oldid=1121103802, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Creative Commons Attribution-ShareAlike License 3.0, 160 to 146C; 256 to 231F; 113 to 127K, This page was last edited on 10 November 2022, at 14:36. Each carbon atom is understood to be attached to enough hydrogen atoms to give each carbon atom four bonds.
4-ethyloctane 3-ethyl-2
A condensed structural formula is a more compact way of representing the structural formula of a molecule. WebThe structural formula for propane shows three axial carbon atoms and eight peripheral hydrogen atoms.
Find compounds which contain this structure, Find compounds which resemble this structure, European Molecular Draw the complete structural formula and the condensed structural formula for isobutane. Isobutane is a colourless, odourless gas. While condensed structures are easier to write than complete structural formulas or partially condensed structures, they can prove to be a little more challenging to determine the three-dimensional bonding pattern of the atoms.
Thus, structural formulas identify the specific isomers by showing the order of attachment of the various atoms.
You'll get a detailed solution from a subject matter expert that 3. Ans: The general formula for the alkanes \({{\rm{C}}_{\rm{n}}}{{\rm{H}}_{{\rm{2n + 2}}}}\) is where \({\rm{n}}\) is the number of carbon atoms in the molecule. Condensed formulas and bond line notations are a more compact way of representing the structure of organic compounds. A structural formula consists of symbols for the atoms connected by short lines representing chemical bondsone, two, or three lines standing for single, double, or triple bonds. Lets learn some of how these compounds can be represented. However, the molecular formulaedo not provide adequate information for chemical analysis.
