In an alkane, each carbon atom is bonded to 4 hydrogen atoms. So, the number of hydrogens in an alkane can be determined by the formula 2n+2, where n is the number of carbon atoms in the alkane.

How many hydrogens are present on an alkane with 20 carbons?

An alkane with 20 carbons will have 42 hydrogens. This can be calculated using the formula 2n+2, where n is the number of carbons (C) in the alkane. So for an alkane with 20 carbons, the number of hydrogens would be 2(20) + 2 = 42.


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.


What is the formula for the alkane containing 100 hydrogens?

The alkane with 100 hydrogen would be C49H100.The 100 hydrogen will have 49 carbons attached.The carbons on the ends would have 3 hydrogen each so the hydrogen left are 94 so the Carbon in the chain can only have 2 hydrogen each.Therefore the no of hydrogen in between will have 47 carbons and two carbons on the end. 47+2 =49 carbons.


How many hydrogens in eicosane?

Eicosane is a straight-chain alkane with the chemical formula C20H42. This means it contains 20 carbon atoms and 42 hydrogen atoms. Therefore, eicosane has 42 hydrogen atoms in total.


Why can the cracking of an alkane into an alkene not be described as oxidation since the alkane loses two hydrogens?

Technically it can be described as oxidation. Technically it is an oxidation reaction, although I've never heard it described as "the oxidation of an alkane". Strange, since when an alkene is converted to an alkane by hydrogenation, we do hear it called "reduction of an alkene". Perhaps this is because the term "alkane oxidation" has been appropriated for the promising research into efficiently capturing energy by combining alkanes with oxygen at low temperatures.


Is methane is the only alkane?

No, there are many alkanes; methane is the simplest alkane.


How many hydrogens are in the molecular formula C22H ClN2O2?

There are 24 hydrogens in the molecular formula C22H ClN2O2.


One molecule has how many atoms of hydrogen?

Answer: Molecules do not necessarily have any hydrogen atoms (e.g. NaCl has only sodium and chlorine and no hydrogen)The lowest number of hydrogens possibly present is one. This occurs in compounds like hydrogen chloride (HCl).Many molecules have two hydrogens, the simplest is hydrogen gas (H2)After this it's open season on hydrogens. Complex hydrocarbons (for example, polyethylene and heavy alkane oils) can have several hundred carbons each with two hydrogens and two extra to cap the ends (general formula : CnHn+2)

What chemical series does methane belong to?

In chemistry, ethanol is a classified as an "alkane". It is also grouped as one of many "hydrocarbons", meaning it consists of only hydrogen and carbon atoms. It is also an "alcohol". I think ethane (alkane) and suffix of alcohol is how its name is derived.
