For a hydrocarbon with 121 carbons, the general formula would be Cβ‚™Hβ‚‚β‚™β‚Šβ‚‚. Therefore, there would be 123 hydrogens in this hydrocarbon (2 more than the number of carbons).

for 21 carbon 44 hydrogen atoms are required if compound is open chain and 42 hydrogen atoms are required if compound is cyclic both type ofcompounds are saturated.

In alkanes carbon is bonded to how many other atoms?

Four. A terminal carbon in an alkane is bonded to 3 hydrogens and 1 carbon, while a middle carbon is bonded to 2 hydrogens and 2 carbons.


How many hydrogens are on a saturated hydrocarbon with 4 carbons?

A saturated hydrocarbon with 4 carbons, which is a butane molecule, will have 10 hydrogen atoms. The general formula for calculating the number of hydrogen atoms in an alkane molecule is 2n + 2, where n is the number of carbon atoms.


What do hydrogen and carbon make?

When hydrogen and carbon combine, they can create various hydrocarbons, such as methane (CH4) or ethane (C2H6). These compounds are the basis for many organic molecules found in nature, including fossil fuels and organic materials.


How many carbon atoms does propane have?

there are 8 hydrogen atoms present in propane. There is 8 hydrogen atoms in propane, Each carbon has a valency of 4, 4 bonds with other atoms. Hydrogen has valency of 1. the general formula for alkanes is CnH2n +2 (n means number of that atom.) so to find how many hydrogens there with, say, 50 carbons you would do CnH2n + 2= C50H102. :)

What fatty acids do not have double bonds beween carbons?

If there are no double bonds, then carbon will take up as many hydrogens as it can, two (three on the ends). Because there are more hydrogens bonded, they are referred to as "saturated" lipids. Unsaturated lipids have double bonds between the carbons and hydrogens. When there is a double bond, one carbon only bonds with one hydrogen - "unsaturated" lipids. The double bonds cause "kinks" in the fatty acid tails, so it is more difficult to "pack" them together. For this reason, they do not solidify at room temperature. However, saturated lipids may solidify at room temperature -- this is how you distinguish between saturated and unsaturated lipids by sight. Examples of saturated lipids (having no double bonds between carbons and hydrogens) are animal fats. "Saturated fats" is a synonym for animal fat on nutritional labels.
