This is a short answer type question as classified in NCERT Exemplar
Ambident nucleophiles are groups that include two nucleophilic centres, such as cyanide and nitrile. In the cyanide group, linkage can occur from both the carbon and nitrogen ends. The carbon end functions as a greater nucleophile in an aqueous media because it leads to the creation of a C-C sbond, which is stronger than a N-C bond in the identical molecule.

In the presence of ZnCl2, ethanol can be treated with HCl to produce chloroethane. Iodoethane is formed when chloroethane reacts with NaI.
C2H5OH+HCl→ZnCl2? C2H5Cl→ NaI ? C2H5I

Resonance effect: Because the C – X bond has the characteristics of a partial double bond, it is extremely difficult to break.
(i) The C - X bond in haloarenes is extremely less reactive to nucleophilic groups
(ii) The C atom linked to the halogen is sp2 hybridised in the C – X bond. Carbon that has been sp2 hybridised with a higher s-character is more electronegative in nature and can retain the electron pair of the C - X bond more tightly than carbon that has been sp3 hybridised with a lower s -character in haloalkanes.

Tert-butyl bromide is substituted via the SN1 process because it may produce a stable carbocation in the first step after the halide group is cleaved. The nucleophile OH - interacts with the carbocation next. The primary halide n-butylbromide, on the other hand, is unable to create a stable carbocation, thus it undergoes the SN2 process, which is a one-step substitution involving OH - attack and concomitant X - leaving to generate n-butyl alcohol.

Because of resonance stabilisation, aryl halides are less reactive to nucleophilic substitution. The inclusion of a -NO2, an electron-withdrawing group in the ortho or para position, enhances the aryl halide's sensitivity to substitution. The more electron withdrawing groups there are in the aryl halide, the more reactive it is. The decreasing sequence of reactivity, according to this theory, is III > II > I.

Nucleophilic substitution and elimination (β-elimination) reactions are both possible with alkyl halides.
Although, with the appropriate reaction conditions and reagent selection, a specific product can be produced. In most cases, the elimination reaction is best suited to strong and bigger bases, as well as high temperatures. The substitution reaction, on the other hand, is best for weaker and smaller bases at lower temperatures.

The IUPAC names for DDT and benzene hexachloride are 2, 2-bis (4-chlorophenyl)-1, 1-trichloroethane and 1, 2, 3, 4, 5, 6-hexachlorocyclohexane, respectively.
They are poisonous and non-bio digestible at the same time. They are fat soluble, and their concentration in the food chain continues to rise. As a result, they are prohibited in India and other nations.

Diphenyls, such as p, p-dichlorodiphenyltrichloroethane (DDT), which have been employed as organic pesticides, are a possible hazard to the environment since it was shown to have significant toxicity towards fish during its early years of widespread use, and many insects acquired resistance to it. The issue was exacerbated by DDT's chemical persistence and fat solubility. In terms of chemistry, DDT is not metabolised or solubilized well by mammals. The fatty tissues are where it is deposited and kept. DDT builds up within the animal over time if it is consumed at a con

The bromine water test and Bayer's test are two methods for detecting the presence of an unsaturated double bond in an organic molecule.
Bromine is added to the carbon atoms across the double bond in the bromine water test when the molecule is introduced to bromine water. Bromine water changes colour from orange to brown to colourless at the end of the process.
The alkaline KMnO4 is employed in Bayer's test to detect unsaturated carbon with a double bond. The chemical produces [O], which hydrolyzes the carbons across the double bond, resulting in a purple-to-colorless s
