Alkyl groups- Alkyl group is formed by removing a hydrogen atom from the molecule of alkane. Alkanes are quite often represented as R-H and here R stands for alkyl group. To learn more about Nomenclature, Types, Formation, Alkyl cation, anion, radicals a
These alkyl groups all have the formula C4H9. Two alkyl groups are derived from butane and two from isobutane. If a primary carbon atom of butane loses a hydrogen atom, an n-butyl group results; if a secondary carbon atom of butane loses a hydrogen atom, a secondary alkyl group, sec-...

As part of doing this, he was also able to show that the work of Gröger,107 whose analysis of the permanganate oxidation product of tallow acid that had led him to propose a molecular formula of C26H52O6, was in error,103 and that the correct molecular formula for the oxidation ...
SOLUTION: A monomer solution is obtained by mixing a monomer mixture containing a divinylbenzene and an alkylstyrene derivative represented by the formula (n is an integer of 3-18), an initiator of polymerization and an organic solvent which is insoluble in water and dissolves the monomer ...
It is formed by removing a hydrogen atom from an alkane chain. For examplemethaneis the simplestalkanewith a chemical formula {eq}CH_4 {/eq}. Methane is converted to a methyl group by the removal of one hydrogen as shown in the diagram, so the chemical formula becomes {eq}CH_3 {/eq...
Liquid crystal compounds exhibiting smectic phases and useful for display elements have the formula: in which R and R are each a C-C alkyl group and X is a hydrogen or fluorine atom. A chiral smectic liquid crystal composition comprises at least one compound of formula (I) together with an...
