Structure and Synthesis of Alcohols. Step 6: If the molecule contains branches or side-chains: (a) condense the structure as for the carbon backbone, (b) use parantheses (round brackets) to enclose groups of atoms attached to the chain, (c) use a subscript number to indicate the number of times this group occurs at that position. Anonymous. Condensed Structural Formula. Using the virtual resource build the extended structural formulas of the following compounds. Click hereto get an answer to your question ️ 4. The formula which only shows the number of carbon and hydrogen atoms present in the molecule without representing the bond present in the molecule is called Condensed structural formula. The formula of the five-carbon alkane pentane is C 5 H 12 so the difference in hydrogen content is 4. The simplest alkane is called methane (CH 4), having the structural formula below.

Formula is a complete and versatile typeface that bold racy condensed look with the flexibility of a grotesque. Thus, structural formulas identify the specific isomers by showing the order of attachment of the various atoms. Thus, structural formulas identify the specific isomers by showing the order of attachment of the various atoms. Draw condensed structural formulas for the following compounds. 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. Structural formulas are often used to show how the atoms share their electrons. Thus, structural formulas identify the specific isomers by showing the order of attachment of the various atoms. a) 3-phenylpentane.

A halogenated hydrocarbon is a molecule that contains carbon, hydrogen and a halogen (Group 17) atom such as fluorine, chlorine, bromine or iodine. Please do not block ads on this website. We haven't shown all of the bonds here but this structure has the same information as the Lewis structure on the left. For the sake of clarity, double and/or triple covalent bonds between carbon atoms are usually shown in the condensed structural formula, or semi-structural formula. Unfortunately, structural formulas are difficult to type/write and take up a lot of space. 2. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. The following are suggested steps for drawing a line-angle structure (also known as a skeletal structure). 3. A structural formula shows all the carbon and hydrogen atoms and the bonds attaching them. Step 4: Re-draw the formula by replacing the identified groups of atoms in the 2-dimensional structural formula with their condensed structure, or semi-structural formula. Re-write the partial structural formula showing how these atoms are bonded to the carbon backbone (skeleton). Unfortunately, structural formulas are difficult to type/write and take up a lot of space. Write the condensed structural formula, or semi-structural formula, for 2-chloropropane (molecular formula C3H7Cl). The formula of the five-carbon alkane pentane is C 5 H 12 so the difference in hydrogen content is 4. Using the virtual resource build the extended structural formulas of the following compounds. step by step so that i may do the rest myself, please. Chemistry: An Introduction to General, Organic, and Biological Chemistry 12th. Some subtle elements set this type apart from the others notably the “t”, “f”, “w” & “Q”. Source(s): https://shorte.im/a7UxI. A condensed structural formula for ethane may be written as: CH 3 CH 3 Since each of the four electrons of carbon are shared with four other atoms, these compounds are termed saturated hydrocarbons. (d) write this group to the right of the carbon atom of the backbone at the position it is located. The condensed formula for pentane is CH 3 (CH 2) 3 CH 3 or CH 3 CH 2 CH 2 CH 2 CH 3. (d) Write this group to the right of the carbon atom of the backbone at the position it is located. This condensed structural formula implies a different connectivity from other molecules that can be formed using the same atoms in the same proportions (isomers). The condensed formula is CH 3 (CH 2) 4 CH 3. What is the Condensed structural formula of: -1,2,3-Trimethyl Cyclohexene-Methanol-Methoxypropane-Ethanal-2-Pentanone-Heptanoic Acid-Methyl Butanoate-Diethylamine-N,N- Dimethyloctanamide??

Step 2: Identify the carbon backbone (or skeleton) and any branches or side-chains in the structural formula as well as any functional groups such as halogen (group 17) atoms. It's easier to visualize a molecule from its condensed formula than from its molecular formula, particularly when there are multiple ways the chemical bonds could form. The 2-dimensional (full display) structural formula for a molecule containing a long hydrocarbon chain, decane (molecular formula C10H22), is shown below: There are no branches or side-chains in this molecule. b) 2,3-dimethylhexane. 3,4-Dimethyl-2-pentene c. 1,6-Heptadiene d. l-Buten-3-yne 1 decade ago.

The LibreTexts libraries are Powered by MindTouch® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. a. Each carbon atom is understood to be attached to enough hydrogen atoms to give each carbon atom four bonds. Section 3. The new condensed structural formula, or semi-structural formula, is therefore (CH3)2CHCl. In early organic-chemistry publications, where use of graphics was strongly limited, a typographic system arose to describe organic structures in a line of text. Chemistry: An Introduction to General, Organic, and Biological Chemistry 12th. Still have questions? Below is an example of a more complicated molecule. Search by Structure or Substructure. 2-Methyl-2-heptanol b. 0 0. peteryoung144. Trending Questions. The condensed structural formula, or semi-structural formula, above can be further condensed by recognising that the eight CH 2 groups occur in a long straight chain (no branches or side chains) so they could be represented as [CH 2] 8.
