According to the Federal Reserve Bureau, the average cost of an annual premium for homeowners insurance is between $300 and $1,000.For most homeowners, the annual costs for a homeowners insurance policy can be estimated by dividing the value of the home by 1,000, then multiplying the result by $3.50.ccording to the Federal Reserve Bureau, the average cost of an annual premium for homeowners insurance is between $300 and $1,000.
Types of structural isomerism Chain isomerism These isomers arise because of the possibility of branching in carbon chains. For example, there are two isomers of butane, C4H10. In one of them, the carbon atoms lie in a straight chain whereas in the other the chain is branched.
Alicyclic compounds can also display cis-trans isomerism. As an example of a geometric isomer due to a ring structure, consider 1,2-dichlorocyclohexane: Optical Isomerism . Main article: Chirality. Optical isomers are stereoisomers formed when asymmetric centers are present, for example, a carbon with four different groups bonded to it. Enantiomers are two optical isomers (i.e. isomers that are reflections of each other). Every stereocenter in one isomer has the opposite configuration in the other.
