In a hydrocarbon chain, one or more hydrogens can be replaced by these elements, such that the valency of carbon remains satisfied. In such compounds, the element replacing hydrogen is referred to as a heteroatom. These heteroatoms confer specific properties to the compound, regardless of the length and nature of the carbon chain and hence are called functional groups.•such a series of compounds in which the same functional group substitutes for hydrogen in a carbon chain is called a homologous series.•The names of compounds in a homologous series are based on the name of the basic carbon chain modified by a “prefix” “phrase before” or “suffix” “phrase after” indicating the nature of the functional group. C + O2 → CO2 + heat and light• CH4 + O2 → CO2 + H2O + heat and light• CH3CH2OH + O2→ CO2 + H2O + heat and light• C2H5OH(KMnO4/K2Cr2O7)χ→CH3COOH. Addition reaction is commonly used in the hydrogenation of vegetable oils using a nickel catalyst. VegeTable oils generally have long unsaturated carbon chains while animal fats have saturated carbon chains. Animal fats generally contain saturated fatty acids which are said to be harmful for health. Oils containing unsaturated fatty acids should be chosen for cooking. Saturated hydrocarbons are fairly unreactive and are inert in the presence of most reagents.A number of products are usually formed with the higher homologues of alkanes.• 2Na + 2CH3CH2OH → 2CH3CH2O– Na+ + H2• C2H5OH→(H2SO4)C2H4+H2O•The molecules of soap are sodium or potassium salts of long-chain carboxylic acids. The ionic-end of soap dissolves in water while the carbon chain dissolves in oil. The micelles stay in solution as a colloid and will not come together to precipitate because of ion-ion repulsion. •Law of Dominance :According to this law, characters are controlled by discrete units called factors that occur in pairs, with one member of the pair dominating over the other in a dissimilar pair.This law explains the expression of only one of the parental characters in F1 generation and expression of both in F2 generation. Law of Segregation: This law states that the two alleles of a pair segregate or separate during gamete formation in such a way that a gamete receives only one of the two factors.In homozygous parents, all gametes produced are similar; while in heterozygous parents, two kinds of gametes are produced in equal proportions.• An ecological pyramid is a graphical representation designed to show the biomass or bio productivity at each trophic level in a given ecosystem. • The progeny formed by sexual reproduction is the result of the combination of the genetic material from two different individuals. So, the offspring acquires half of the traits from the mother and half from the father. Thus, the combination of various traits results in the variation in the offspring due to which the offspring is different from both the parents. Crossing over is the process in which the DNA is exchanged between the homologous chromosomes during meiosis. It occurs during gamete production, and as a result of this the gametes produced by an individual do not have the same genetic material as of the individual. This adds to the variation as the genetic material of an organism is recombined before formation of gametes and the recombined gametes fuse to form the zygote which gives rise to the offspring. So, the offspring will not have exact set of genes from the parents but will have recombined set from each of them.• Mendeleev's law states that the physical and chemical properties of the elements are the periodic function of their atomic masses. • A monohybrid cross is when the offspring of homozygous parents that only differ on a single trait are bred to come up with the second generation. On the other hand, a dihybrid cross is pretty similar to a monohybrid cross except that the parents of the first generation differ in two traits. Mendel crosses varieties of pea plants that differed in more than one characters from each other by two pairs of genes. This is called dihybrid cross
