Q. The alkyl halides that can be made by free radical halogenation of alkanes are
A) $RCl\$and $RBr$ but not $RF\ or\ RI$
B) $RF,\ RCl\$and $RBr$ but not RI
C) $RF,\ RCl,\ RBr,\ RI$
D) $RF,\ RCI\ and\ RI\$but not $RBr$
Explanation
(a)
RCl and RBr can be prepared by free radical halogenation of alkanes while RF and RI cannot be prepared. With $F_{2}$, the reaction is not only explosive but also brings cleavage of C-C bonds while with $I_{2}\$the reaction is too slow to be of any practical value.
