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.
3. Carbon can form double and triple bonds with other carbon atoms or other elements. 4. Carbon can bond with itself either as straight chains or cyclic compounds with branching possible in either case. Two different organic compounds can also have the same number of carbon atoms.These are called isomers.Isomers are molecules that have the same molecular formulas but different structures and thus different physical and chemical characteristics. An example of isomerism is butane and 2-methylpropane.thane, C2H6, is an alkane and is an example of a saturated hydrocarbon. Ethene, C2H4, is an alkene and is an example of unsaturated hydrocarbon. Ethyne, C2H2, is an alkyne and is also an example of unsaturated hydrocarbon. Aromatic compounds are unsaturated hydrocarbons and contain a benzene ring.
