The cost is $15 for the permit and we have the forms in the office. You get the permit the same day and it is good for one year. All you need is your drivers license and you can not be within 6 months of your expiration date. You also need two standard passport photos which we can take in the office.
There are three types of unsaturated hydrocarbons: alkenes, alkynes and aromatic hydrocarbons. Alkenes are unsaturated hydrocarbons that have one or more carbon-carbon double bond, with a general structure of (R-C=C-R'), where R and R' are hydrocarbon groups attached to either side of the carbon atoms.
Hydrocarbons that contain rings or double bonds are called unsaturated hydrocarbons, which are the opposite of saturated hydrocarbons. Alkanes-such as cyclohexane, which is an important precursor to nylon-that contain rings of carbon atoms are unsaturated. Another example of a hydrocarbon is ethylene.ydrocarbons with carbon-carbon double bonds are called alkenes. Hydrocarbons with carbon-carbon triple bonds are called alkynes. And hydrocarbons that contain rings of carbon atoms that are joined by alternating single and double bonds are called aromatic.
