Hydrogen is attached to carbon molecule with single bond and not double bond because the hydrogen atom joins to one of the carbon atoms originally in the double bond.
Single, double, and triple carbon-carbon bonds; carbon-hydrogen bonds; carbon-halogen bonds; hydrogen-hydrogen bonds; nitrogen-nitrogen bonds; single and double carbon-oxygen bonds; silicon-oxygen bonds in silicone polymers.
Simple answer ... you need at least one hydrogen attached to carbinol carbon. in other words, you have a hydrogen on the oxygen to give you the hydroxyl group that is attached to the carbinol carbon, but you also need a hydrogen coming off that carbon. The reason - your reagent, such as chromic acid, joins with the alcohol at the position of the hydroxyl group, which leads to an H2O molecule being shot off. The chromic acid provides the -OH of that water, but takes the H off the hydroxyl group to get the 2nd hydrogen atom. You would now have a chromate ester + water. The water then takes off a hydrogen atom attached to the carbinol carbon, which leaves the electrons to form a double bond with the Oxygen atom. Without the hydrogen attached to the carbinol carbon ... like in a tertiary alcohol ... oxidation could only take place by breaking carbon-carbon bonds, which requires severe conditions. Even if this did happen, you would get a mixture of products.
Glucose is called a 6 carbon sugar because there are six carbon atoms along its back bone, which are either attached to a hydrogen in one side and a hydroxyl group (OH) to the other side. the very fist carbon i attached to a hydrogen by a single bond, and to an oxygen by a double bond, while your last carbon besides being attached to the hydrogen and hydroxyl group it also has another hydrogen attached to it. All are attached by single bond with the exception of that one oxygen.
A saturated fat. Saturated with hydrogen at the bonding site freed up by lack of carbon-carbon double bonds. This fat packs tightly and is solid at room temperature.
The difference between a saturated and unsaturated fatty acid are the number of hydrogen atoms and double carbon bonds in the fatty acid chain. A saturated fatty acid has no carbon double bonds, two hydrogen atoms for each carbon atom along the chain and three for the carbon atom at each end. In an unsaturated fatty acid chain some of the hydrogen atoms are replaced by a double bond between neighboring carbon atoms. Mon-unsaturated and poly-unsaturated fatty acids differ in the number of double carbon bonds in the chain, and thus the total number of hydrogen atoms.
Carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. The defining structure is a nitrogen attached to a carbon that is attached to another carbon that is double bound to an oxygen. The nitrogen side is called the Amino terminal, and the other side is called the carboxy terminal. What makes amino acids different is the R group that is attached to the first carbon I mentioned with the simplest being a hydrogen. N | C-R | C=0 | O Hydrogen not shown to simplify.
Imines are those compounds in which nitrogen is attached to a carbon through double bond and to hydrogen through single bond, R-CH=N-H, carbon and nitrogen both are sp2 hybridized, they behave just like unsaturated hydrocarbons
The number of hydrogen atoms attached to the carbon backbone is the lowest in unsaturated fats (in contrast to saturated fats). This is due to double-bonding.
They both fall under the Organic Functional Group "amide", meaning they both have a double bonded oxygen and a nitrogen + a hydrogen attached to a carbon.
In fatty acids, having no carbon-carbon double bond makes the molecule saturated with hydrogen atoms.
Single, double, and triple carbon-carbon bonds; carbon-hydrogen bonds; carbon-halogen bonds; hydrogen-hydrogen bonds; nitrogen-nitrogen bonds; single and double carbon-oxygen bonds; silicon-oxygen bonds in silicone polymers.
Ethylene has 4 single bonds (carbon to hydrogen) and 1 double bond (carbon to carbon).
Carbon and hydrogen. Benzene is a hexagonal ring formed of carbon-carbon bonds, alternatively double and single. http://i205.photobucket.com/albums/bb157/hortaux/benzene.jpg

There are 10 hydrogen atoms in an unbranched alkene with 1 double bond and 5 Carbon atoms
Formaldehyde, H2C=O, is the basic member of organic compounds known as aldehydes. Aldehydes are hydrocarbons (chains of carbons with hydrogen attached) with an oxygen atom double-bonded to a carbon.
