(iii) Bromination of alkenes	(c) Racemisation
(iv) Alkylidene halides	(d) Saytzeff rule
(v) Elimination of HX from alkylhalide	(e) Chlorobromocarbons

<p><span data-teams="true">This is a matching answer type question as classified in NCERT Exemplar</span></p><p>Racemization is the process of converting enantiomers into a racemic mixture, which is a mixture comprising two optically active enantiomers in equal quantities, from the results of the <strong>S_N</strong><strong>¹</strong> reaction. Chemical fire extinguishers are chlorobromocarbons.</p><p>Bromination of alkenes produces vic-dibromides, which are formed when halogen atoms of the same kind are linked to nearby carbon atoms of the molecule. Alkylidene dihalides, sometimes called gem-dihalides, are dihalides that have two halogen atoms bonded to the same carbon atom. The Saytzeff rule governs the removal of&nbsp;<strong>HX</strong> from alkyl halides: “In dehydrohalogenation processes, the desired product is that alkene with the greatest number of alkyl groups linked to the doubly bound carbon atoms.”</p><p><strong>Correct Answer:</strong> (i)&nbsp;→&nbsp; (c) (ii)&nbsp;→&nbsp; (e) (iii)&nbsp;→&nbsp; (a) (iv)&nbsp;→&nbsp; (b) (v)&nbsp;→&nbsp; (d)</p>
