They are nonpolar molecules so they are insoluble in water. An aliphatic hydrocarbon is a hydrocarbon arranged ina chain. There are three types of aliphatic hydrocarbons. Alkanes consist on only single carbon-carbon single bonds. They are saturated, meaning that every carbon atom has 4 bonds. The formula for an alkane is CnH2n+2. Alkanes have a tetrahedral geometry and a bond angle of 109.5o. Alkenes have at least one carbon-carbon double bond. They are unsaturated since not every carbon atom will have four bonds. The double bond leads to a trigonal planar geometry and the double bonded atoms will have a bond angle of 120o. The formula for alkenes is CnH2n. Alkynes have at least one carbon-carbon triple bond and are unsaturated. The triple bond leads to a linear geometry and an 180o bond angle. The formula is CnH2n-2.III. IsomersIsomers have the same chemical formula but their atoms are connected differently. Constitutional isomers have different connectivity. A rotation about a single bond does not make an isomer. Geometric isomers have the same chemical formula, same connectivity, but have different atom arrangements. These isomers only occur when there is a double or triple These notes represent a detailed interpretation of the professor’s lecture.
