homologous series in a sentence

Examples

1. Thus, these compounds form a homologous series with chemical formula in which the members differ by a constant relative molecular mass of 16 ( the mass of each additional oxygen atom ).
2. Much of the early work establishing that silicon does indeed form a homologous series of hydride analogous to the alkanes, albeit to a much smaller extent, was conducted by Alfred Stock and Carl Somiesky.
3. Evidence that cutan is a hydrocarbon polymer comes from the fact that its flash pyrolysis products are a characteristic homologous series of paired alkanes and alkenes ( Nip " et al . " 1986)
4. The corresponding homologous series of primary straight-chained alcohol comprises methanol ( CH 4 O ), ethanol ( C 2 H 6 O ), 1-propanol ( C 3 H 8 O ), 1-butanol, and so on.
5. The homologous series of straight-chained alkanes begins methane ( CH 4 ), ethane ( C 2 H 6 ), propane ( C 3 H 8 ), butane ( C 4 H 10 ), and pentane ( C 5 H 12 ).
6. Analysis of the extracts revealed homologous very-long-chain 1, 3-alkanediols, homologous series of C31, C33 and C35 alkanols, protoquercitol, methyl-D-fructopyranoside, palmitic acid, stearic acid, linoleic acid, linolenic acid and their methyl esters.
7. Vavilov's ideas regarding the law of homologous series in hereditary variation gives the answer to the question of " which " material should be sought, while the theory of the centers of origin of cultivated plants responds to the question of " where " it should be sought.
8. With their repeated-CH 2-units, the alkanes constitute a homologous series of organic compounds in which the members differ in molecular mass by multiples of 14.03 methylene-bridge unit, which comprises a single carbon atom of mass 12.01 u and two hydrogen atoms of mass ~ 1.01 u each ).
9. In literature, " nor " is sometimes called the " next lower homologue ", although in this context " homologue " is an inexact term . " Nor " only refers to the removal of one carbon atom with the accompanying hydrogen, not the removal of other units . " Nor " compares two related compounds; it does not describe the relation to a homologous series.
10. P 4-" t "-Bu can also be regarded as tetrameric triaminoiminophosphorane of the basic structure ( H 2 N ) 3 P = N-H . The homologous series of P 1 to P 7 polyaminophosphazenes of the general formula \ mathrm { [ ( R ^ 1 _ 2N ) _ 3P = N-] _ x-( R ^ 1 _ 2N ) _ { 3-x } P = NR ^ 2 } with preferably methyl groups as R 1, a methyl group or tert .-butyl group as and even-numbered x between 0 and 6 ( P 4-" t "-Bu : R 1 = Me, R 2 = " t "-Bu und x = 3 ) has been developed by Reinhard Schwesinger; the resulting phosphazene bases are therefore also referred to as Schwesinger superbases.
