Hint: Alkyl halide is a compound in which hydrogen is replaced by a functional group, i.e. halogens (fluorine, chlorine, bromine or iodine). ‘Halide’ is another name for ‘halogens’. The compounds containing one, two or more (three, four…) halogens are called mono, di, poly-halogen compounds respectively.
Complete step by step answer:
Alkyl halides are also called haloalkanes. Alkyl halides are those compounds in which one or more hydrogen atoms in an alkane have been replaced by halogen atoms (fluorine, chlorine, bromine or iodine). The general formula of alkyl halides is - \[{{C}_{n}}{{H}_{2n+1}}X\].
Or, in simpler words, alkyl halides are those compounds in which a halogen atom is bonded to an alkyl group. They are classified as primary, secondary, tertiary according to the nature of carbon to which the halogen is attached. It can be represented as –R’’’
(R – Alkyl group; X – halogen)
Therefore, the answer is – option (b) – The secondary alkyl halide is called secondary because the functional group is attached to the secondary carbon atom.
Additional Information:
Alkyl halides are \[s{{p}^{3}}\]hybridized compounds. Other than this, allylic halides and benzylic halides are also \[s{{p}^{3}}\] hybridized compounds.
Note: The compounds which contain \[s{{p}^{2}}\] C-X bond are divided into two categories –
Vinylic halides
In these compounds, halogen is bonded to \[s{{p}^{2}}\] hybridized carbon atom of C-C double bond.
Aryl halides
In these compounds, halogen is bonded to \[s{{p}^{2}}\] hybridized carbon atom of aromatic ring.
