Dihaloalkanes with two halogen atoms linked to the same carbon atom are known as gem-dihalides. Alkylidene halides are another name for them. The chemical ethylene dichloride is a vicinal dihalide, meaning that chlorine atoms are linked to neighbouring carbon atoms. There is only one chlorine atom in benzoyl chloride. According to the molecule's nomenclature, ethylidene chloride is a gem-dihalide. The IUPAC terminology for methylene chloride is dichloromethane. Two chlorine atoms are joined to a single carbon atom in this compound.

Correct Answer: Option (i) and (iii)

Option (i) and (iv) have a halogen atom linked to an sp³ hybridised carbon that is single-bonded to other groups. The other possibilities are sp² hybridised because they are linked to carbon atoms, which are coupled to other groups in double bonds. Option I and (iv) are both correct.

Correct Answer: Option (i) and (iv)

The reaction is of the type S_N¹ nucleophilic substitution. This sort of reaction is governed by second order kinetics, in which the rate of reaction is determined only by the concentration of the reactant. A reaction's molecularity is defined as the number of molecules involved in the rate-determining phase. Because of second order kinetics, the moleculeity of this reaction is one. (i) and (iii) are the right answers .

Correct Answer: Option (A) and (C)

Because it is a tertiary alkyl halide, the described reaction is a nucleophilic substitution that follows the S_N¹ mechanism. It's a two-step process. The first step is the gradual breaking of a polarised C-Br bond, which results in the formation of a carbocation and a bromide ion. To complete the substitution, the stable intermediate carbocation is attacked by the nucleophile OH⁻. (i) and (iv) are the right statements.

Correct Answer: option (A) and (iv)

Because the carbon atom is transiently linked to five atoms, the intermediate (iii) is less stable than reactant (ii), which is coupled to four groups.

An S_N² reaction, also known as a nucleophilic substitution, is the reaction in question. The entering nucleophile causes the groups surrounding the carbon atom to migrate in the opposite direction of the nucleophile, causing the configuration of alkyl halides to invert. As a result, (b) and (d) will be in the opposite order. This reaction is also S_N² since there is just one phase in which OH^- is added and Cl^-  is removed at the same time. (i) and (ii) are the right answers.

Correct Answer: Option (A) and (B)

This is a multiple choice answer as classified in NCERT Exemplar

An S_N² nucleophilic substitution reaction occurs when CH³Cl interacts with the hydroxide ion to produce CH³OH. Both OH -  and Cl - are nucleophiles with an excess of electrons in this reaction. Because the binding of OH -  and the leaving of Cl - occurs simultaneously in the transition state (c), the carbon atom is linked to just three hydrogens. As a result, the carbon atom becomes sp² hybridised.  Aand (C) are the right statements.

Correct Answer: Option (A) and (C)

The Correct Answer is Option (iv).

If the halogen atom in all of the supplied alkyl halides is the same kind, the boiling point of a compound rises as the number of alkyl groups added increases. As the quantity and size of molecules and electrons grow, so do their attractions. As a result, the greater the boiling point, the larger the molecular weight of the alkyl halide. The boiling points of the following compounds are listed in ascending order: 1-Bromoethane 1-Bromopropane 1-Bromobutane Bromobenzene The right answer is (iv).

The Correct Answer is Option (i).

The intermolecular force of attraction will grow as the surface area increases. As a result, the boiling point rises as well. The boiling point of a comparable alkyl halide rises with increasing molecular mass. Iodine has the greatest atomic mass. As a result, 1-iodobutane has the greatest boiling point.
