So, its like. 5) Alkenes and alkynes are called unsaturated compounds because A) they have the maximum number of hydrogen atoms attached to each carbon in the compound. Seven Carbon atoms and 16 Hydrogen atoms. An alkane with seven carbon atoms can be drawn multiple ways. For example, in the carbon dioxide (CO 2), the carbon has two double bonds, but it is sp-hybridized. So Heptane is: C7H16. So, we have C7H? An alkane, like heptane, contains twice as much hydrogen atoms as its carbon plus 2. Normally a chiral molecule contains at least one chiral carbon. C) they have more hydrogen atoms attached to the carbon chain than alkanes. It is a flammable liquid that gives out fumes at room temperature and has a flash point of -4°C (24°F), hence a narrow boiling point. In this case, C3 is an example of a tertiary carbon. This means based on the classification described above, C1 is a primary carbon. Heptane is a hydrocarbon molecule which contains 7 carbons and 16 hydrogens. E) octane. Now, let's get Hydrogen's subscript. Ch. Twice 7 + 2 is 16. sp or sp2 hybridized carbon atoms cannot be chiral because they cannot have four different groups around them due to the presence of π-bonds. ... Ch. D) heptane. The alkane shown has seven carbons in its longest chain and is therefore named as a derivative of heptane, the unbranched alkane that contains seven carbon atoms. Hence, C 5 H 12 is called pentane , C 6 H 14 is called hexane , C 7 H 16 is called heptane and so forth. It is thought to promote resistance to UV and 4-hydroxy-2-nonenal-induced oxidative damage in the cornea. B) they have fewer hydrogen atoms attached to the carbon chain than alkanes. To which carbon atoms in a heptane molecule can each of the following alkyl groups be attached without extending the longest carbon chain beyond seven carbons? Alkanes are described as saturated hydrocarbons, while alkenes, alkynes, and aromatic hydrocarbons are said to be unsaturated. The carbon atom should always be sp 3 hybridized in order to be a chiral carbon. The numbers in front of the names represent the carbon atoms that contain methyl groups on the molecular chain. Here we assume the straight-chain version, known as n-heptane. H= 2C + C. So, hepta is the prefix which corresponds to 7. Heptane is an alkane that consists of seven carbon atoms and 16 hydrogen atoms: straight-chained saturated hydrocarbon. It naturally exists in nine isomeric forms that include two enantiomers. In addition to hydrogen, other elements may be bound to the carbon atoms in the chain, including oxygen, nitrogen, chlorine, and sulfur. Alkanes with five or more carbon atoms are named by adding the suffix -ane to the appropriate numerical multiplier, except the terminal -a is removed from the basic numerical term. The 2D chemical structure image of HEPTANE is also called skeletal formula, which is the standard notation for organic molecules. a. Ethyl b. On the other hand, C2 is connected to only 2 hydrogen atoms and 2 other carbon atoms. Therefore, it is asymmetric. In this case, C2 is considered a secondary carbon. Lastly, C3 is connected to only one hydrogen atom and three other carbon atoms.
