Place hydrogen atoms in all of the unoccupied posi. Hydrocarbons are made of hydrogen and carbon atoms. Hydrocarbons naming and writing chemical formulas youtube. Of the following molecular formulas for hydrocarbons. This means that the number of hydrogen atoms equals twice the number of carbon atoms, plus two. Use a molecular model kit to build a structure with two carbon atoms connected by a single bond. At the end of the video students will be given a set of. Thus you can consider c2h6 as derived from ch4 by replacing one hydrogen atom by ch 3 group. Write the mathematical formula for the ratio of carbon to hydrogen for each compound to determine the pattern. Of the following molecular formulas for hydr ocarbons, which is an empirical formula. Aromatic hydrocarbons 26 draw the bondline structures and determine the chemical formulas for hexane, 1hexene, cyclohexane, and cyclohexene. These compounds comprise a distinct class, called aromatic hydrocarbons. It simply represents four carbon atoms joined in a chain and is just a somewhat misleading way of writing the struc tural formula for an nbutane molecule. The important fuels like petrol, kerosene, coal gas, cng, lpg etc.
Specifically, they are constitutional or structural. The group of saturated hydrocarbons includes alkanes and cycloalkanes. Contain single carboncarbon bonds only unsaturated. Hydrocarbon, any of a class of organic chemical compounds composed only of. Petroleum and natural gas are the major sources of aliphatic hydrocarbon while coal is an important. If you are given a formula, is the first element hydrogen. Next we consider a class of hydrocarbons with molecular formulas like those of unsaturated hydrocarbons, but which, unlike the alkenes, do not readily undergo. Aromatic hydrocarbons are compounds that contain a benzene ring. These compounds comprise a distinct class, called aromatic hydrocarbons, with unique structures and properties. Which of the following statements interpret this information correctly.
This hydrocarbon with molecular formula c2h6 is known as ethane. The formula which shows the actual number of each type of atom saturated. This general formula holds for all noncyclic saturated hydrocarbons. Petroleum and natural gas are the major sources of aliphatic hydrocarbon while coal is an. The structures of alkanes and other organic molecules may also be represented in a less detailed manner by condensed structural formulas or simply. Hydrocarbon is a compound consisting of hydrogen and carbon only molecular formula. Recall that carbon has four valence electrons and it can form four covalent bonds. Analyze the pattern of the carbontohydrogen ratio to develop a generic formula for hydrocarbons with single bonds. Next we consider a class of hydrocarbons with molecular formulas like those of unsaturated hydrocarbons, but which, unlike the alkenes, do not readily undergo addition reactions. In this video we will learn how to name and writhe the chemical formulas for several types of hydrocarbons.
