Vedclass · Answer

(B) For an alkane to produce only one mono-chloro product,all hydrogen atoms in the molecule must be equivalent.Neopentane ($2,2-$dimethylpropane) has the structure $C(CH_3)_4$.In neopentane,all $12$ hydrogen atoms are attached to equivalent primary carbon atoms.Therefore,substitution of any of these $12$ hydrogen atoms by a chlorine atom results in the same product,$1-$chloro$-2,2-$dimethylpropane.Other options like $n-$pentane,isopentane,and $2,2-$dimethylbutane contain non-equivalent hydrogen atoms,leading to a mixture of isomeric mono-chloro products.
