3
4

2

Solution :`{:(overset(1)(C)H_(3)-overset(2)(C)H-overset(3)(C)H_(2)-overset(4)(C)H_(3)),("|"),(""CH_(3)):}`
Its monochloro derivatives are as follows :
(i) `{:(ClCH_(2)-overset(*)(C)H-CH_(2)-CH_(3)),("|"),(""CH_(3)):}`
or `{:(CH_(3)-overset(*)(C)H-CH_(2)-CH_(3)),("|"),(""CH_(2)Cl):}`
It will exist as enantiomeric pair (d and l-forms)
(ii) `{:(""Cl),("|"),(CH_(3)-C-CH_(2)-CH_(3)),("|"),(""CH_(3)):}`
no asymmetric C-atom
(iii) `{:(""Cl),("|"),(CH_(3)-CH-CH-CH_(3)),("|"),(""CH_(3)):}`
It will exist as enantiomeric pair (d-and l-forms)
(iv) `{:(CH_(3)-CH-CH_(2)-CH_(2)-Cl),("|"),(""CH_(3)):}`
No asymmetric carbon atom
Hence, only TWO enantiometric pairs will be obtained by the monochlorination of 2-methylbutane.
