Chapter Description Of Class 12 Chemistry Chapter 10 – Haloalkanes And Haloarenes
Class 12 Chemistry Chapter 10 Haloalkanes And Haloarenes teaches that the common names of alkyl halides are derived by naming the alkyl group followed by the halide. This chapter helps to define several haloalkanes and haloarenes as per the IUPAC system of nomenclature. From this, you can easily describe the reactions which are involved in the preparation of haloalkanes and haloarenes. Understanding these reactions become of utmost importance for your examinations.
This NCERT Chapter 10 lays out an important correlation between the structures of haloalkanes and haloarenes. These get useful when you study organic chemistry closely. Moreover, you will be faced with stereochemistry from which you can understand the reaction mechanism. This chapter gives the potential dimension where you can appreciate the applications of organometallic compounds adequately. The NCERT Solution for Class 12 Chemistry Chapter 10 provided will serve as the guiding element whenever you come across any problems.
NCERT Solutions For Class 12 Chemistry Chapter 10 – Haloalkanes And Haloarenes PDF
An important thing to note here is that these NCERT Solutions for Class 12 Chemistry Chapter 10 are prepared by our experts. These solutions are prepared in a step-by-step manner so as to give a better understanding of the related concepts. Given below are some of the examples taken from the solution PDF. It will help you take a brief look at how our experts have prepared these solutions.
Q: Explain why the dipole moment of chlorobenzene is lower than that of cyclohexyl chloride?
A: The dipole moment is Vector Quantity. In chlorobenzene, the Cl-atom links itself to an sp2 hybridized carbon atom. In cyclohexyl chloride, the Cl-atom is linked to an sp3 hybridized carbon atom. Now, sp2 hybridized carbon has more s-character than sp3 hybridized carbon atom. Therefore, the former is more electronegative than the latter, Therefore, the density of electrons of the C − Cl bond near the Cl-atom is less in chlorobenzene than in cyclohexyl chloride.
Moreover, the -R effect of the benzene ring of chlorobenzene decreases the electron density of the C − Cl bond near the Cl-atom. As a result, the polarity of the C − Cl bond in chlorobenzene decreases. Hence, the dipole moment of chlorobenzene is lower than that of cyclohexyl chloride.
Q: Arrange the compounds of each set-in order of reactivity towards Sn2 displacement: 2-Bromo-2-methylbutane, 1-Bromopentane, 2-Bromopentane
A: An SN2 reaction involves the approaching of the nucleophile to the carbon atom to which the leaving group (−Br) is attached. When the nucleophile is sterically hindered; then the reactivity towards SN2 displacement decreases. Due to the presence of substituents, a hindrance to the approaching nucleophile decreases SN2 order 1 ?> 2 ?>3 ? (alkyl halide).
1-Bromopentane > 2-bromopentane > 2-Bromo-2-methylbutane (nu − approach tendency)
Hence, the increasing order of reactivity towards Sn2 displacement is: 2-Bromo-2-methylbutane < 2-Brornopentane < 1-Bromopentane
Q: What are ambident nucleophiles? Explain with an example.
A: Nucleophiles having two nucleophilic sites are ambident nucleophiles. Hence, ambident nucleophiles have two sites through which they can attack. Nitrite ion is an example of an ambident nucleophile.
Nitrite ion can either attack through oxygen resulting in the formation of alkyl nitrites or it can attack through nitrogen resulting in the formation of nitroalkanes.

Q. What are Haloalkanes Class 12?
A. Haloalkanes and Haloarenes are formed by replacing a hydrogen atom with a halogen atom in an aromatic or aliphatic hydrocarbon. Thus, haloalkanes are created with the substitution of H-atom in aliphatic hydrocarbon, and the exact replacement in aromatic hydrocarbon gives rise to Haloarenes.
