Carbon can form double bond, but chlorine will not form double bond.
Saturated hydrocarbons have every possible bonding site on the carbon backbone that could bond to a hydrogen bonded to a hydrogen. All carbon-carbon bonds are single. These hydrocarbons are rigid and have high melting temperatures. Lard, Crisco, Butter, and Margarine are saturated.Unsaturated hydrocarbons don't and therefor contain one or more double or triple carbon-carbon bond(s). These hydrocarbons are "floppy" and have lower melting temperatures. Cooking and Salad oils are unsaturated.
Organic compounds are those which contain carbon bonds in them. Inorganic compounds dont have carbon (with a few exceptions).
Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings. Also, carbon atoms bond fairly readily with other carbon atoms. It's much more energetically favorable for, say, a silicon atom to bond with an oxygen atom than another silicon atom; with carbon, the difference is less, so carbon-carbon bonds are more stable in the presense of oxygen than silicon-silicon bonds are... this is important, given that oxygen is the third most common element in the universe.
Propane is an alkane and as such, contains only single covalent bonds, so it is considered saturated because each of its carbon atoms is single bonded with a hydrogen atom or another carbon atom.
: : O=C=O : :Sure looks like two double, sigma and pi, bonds between the carbon and the two oxygen atoms. Those dots are the lone pairs, just not put in proper place, which is above and below the oxygen atoms.
Only some cyclic carbon atom rings can properly be called aliphatic: those without any carbon-carbon double bonds or aromatic ring bonds. For example, cyclohexane is aliphatic, but cycolohexene and benzene, which all contain rings of six carbon atoms, are not.
There are many compounds that exhibit tetrahedral structure. Some of those compounds are carbon tetrachloride (CCl4), chloroform (CHCl3), and methane (CH4). Many compounds of carbon (those which don't contain double bonds) are tetrahedral in structure because carbon tends to form four single bonds.
All fats contain chains of carbon atoms bonded to hydrogen atoms. In a saturated fat the carbon atoms in the chains are boned to as many hydrogen atoms as possible (that is, 2 each, with the last carbon bonded to 3) and all carbon-carbon bonds are single bonds. In an unsaturated fat some of the carbons are not bonded to the maximum number of hydrogen atoms, and those carbon atoms that are missing hydrogen atoms are double bonded to a neighboring carbon.
Those with double or triple carbon bonds, so that would be C2H4 and C3H6.
Carbon based molecules are those that have one or more Carbon to Carbon bonds in them, also known as Organic molecules. There are a lot of them.
Benzoic acid is unsaturated because it has double- double carbon bonds and due to resonance those bonds can be easily move around , that's what makes benzoic acid unique. All compounds containing a benzene ring are actually unsaturated.
The energy in a glucose molecule is stored in the bonds between the atoms.
Organic compounds have frequently double or triple bonds.
This is easy to figure out, and it doesn't even matter what isomer of pentane we're talking about: There are five carbons. Each carbon can form four single bonds. Therefore, there must be a total of 5x4 = 20 single bonds, no matter how we arrange the carbon skeleton. Some of those (specifically, four) will be carbon-carbon bonds, and the remainder (sixteen) will be carbon-hydrogen bonds.
carbon's electronegativity is about 2.4 or 2.5, so the electronegativity difference with other elements leads to sharing of electrons. Since carbon has 4 outer shell electrons it needs to form 4 bonds. If there are not enough other atoms to form all these bonds to become stable carbon atoms will form bonds with other carbon atoms. If there are insufficient hydrogen atoms to form single bonds then two adjacent carbon atoms will form multiple (double or triple) bonds in order for the outer energy level to 'get' 8 electrons and become stable.

Butter is a type of oil made from saturated fat, which are made from hydrocarbon molecules. A hydrocarbon is a compound containing only carbon-carbon and carbon-hydrogen bonds. Both of those are covalent bonds.
