Web28 jul. 2024 · Assertion(A) : If the first member of a homologous series is methanal, its third member will be propanal. Reason (R) : All the members of a homologous series show similar chemical properties. ... Reason (R) : Addition reactions are a characteristic property of unsaturated hydrocarbons. Answer (d) Q.10. Web23 jul. 2024 · alkenes are a series of hydrocarbon molecules (made of carbon and hydrogen atoms). They are referred to as 'unsaturated' hydrocarbons because they have a carbon=carbon C=C double bond and other atoms can add to them via simpleaddition reactions.

Web27 mrt. 2012 · Odor detection thresholds (ODTs) are used for assessing outdoor and indoor air quality. They are obtained experimentally by olfactometry and psychophysical methods, and large compilations are available in the literature. A non-linear regression equation was fitted to describe the ODT variability of 114 aliphatic compounds based on the alkyl chain … WebThere are huge numbers of organic compounds, but they fall into families known as homologous series. All the members of a homologous series have the same type of bonding. The homologous series of the alkanes only has carbon-hydrogen bonds and carbon-carbon single bonds apart from methane, CH 4 , the first member of the series … WebHomologous series is a family of organic compounds bearing the same active group (functional group). Members of the same homologous series have the same chemical properties but because they contain different number of carbon atoms their physical properties such as, boiling point, density, conductivity, melting point, solubility, etc differ. dr rothert radebeul
