no, single, double, and triple are allowed. That is what makes organic chemistry so flexible.
No, carbon can from double and triple bonds as well.
A single carbon atom can bond with up to four other atoms.
There are 2 types of atoms. Carbon and the other type is Oxygen. 2 Oxygen atoms are bonded to a single Carbon atom.
Nitrogen can form single, double, and triple bonds with carbon. The triple bond form is called cyanide.
such a hydrocarbon is a saturated compound.

Alkanes have carbon atoms bonded by single bonds, and follow the formula CnH2n+2. Alkenes on the other hand always have one double bond somewhere between a pair of carbon atoms, explaining why they follw the general formula CnH2n.
Atoms of elements have a fixed number of electrons that can bond with other atoms. Carbon has 4 electrons that can bond with other atoms. So 4 hydrogen atoms can bond with one carbon atom.
There are 2 types of atoms. Carbon and the other type is Oxygen. 2 Oxygen atoms are bonded to a single Carbon atom.
Alkanes have ordinary covalent single carbon-carbon bonds and carbon-hydrogen bonds. Alkenes have double carbon-carbon bonds.
Nitrogen can form single, double, and triple bonds with carbon. The triple bond form is called cyanide.
such a hydrocarbon is a saturated compound.
Carbon atoms are arranged in a tetrahedral fashion. Four carbon atoms will form single covalent bonds around the central atom all at the maximum angle away from each other (approx 109 degrees). These four are then joined by a further three carbon atoms again all having single covalent bonds. These bonds just keep forming. Use this link, below, to get a view of it: the black dots represent carbon atoms and the lines are single covalent bonds.In a diamond, the carbon atoms are arranged tetrahedrally.

A saturated hydrocarbon is one where all the carbon atoms are bonded to four other atoms. An unsaturated hydrocarbon is one where some of the carbon atoms aren't (an example being an alkene due to the carbon carbon double bond).
Ethane has two carbon atoms and six hydrogen atoms (C2H6). It is a flammable gas and is a saturated molecule, meaning that each carbon atom has four bonds linked to 4 other atoms. Methane (CH4), propane (C3H8) and butane (C4H10) are similar molecules and all are flammable gases. Ethene has two carbon atoms and four hydrogen atoms (C2H4). It is also a gas but it is an unsaturated molecule: the two carbon atoms are linked by a double bond. Ethene molecules can join together into a single, long molecule. The result is a string of carbon atoms that each have two hydrogen atoms attached and are also linked to two other carbon atoms. This is polythene or polyethelene, a simple polymer that is used for plastic bags among other things. The ability to form into long chains is due to the double bond between the carbon atoms in the ethene molecule.
