Question

Warm up 1. Identify if each compound below is a primary, secondary, or tertiary alkyl halide. 2. Identify the most stable radical of the compound series below (HINT: radicals and carbocations are electron deficient and are similarly stabilized/destabilized by substituents. See Table 8.7) 1B) "O o oo | B) Br ~ ~ ~ "

Answer 1

The answer is given in the attachment.
1ma • When halide group is attached with one carbon that is called primary allys halide, when attached with two carbon that is called - secondary halide Calkyl halide) • when attached with three carbon that is called tertiary halide (allys halide) OD SBY HODEC dam nar primary secondary tertiary secondary. ide la 1 i sadical 3sodical &radial 2 radical. (in primary stability of radicals 720 - Secondary 30 testiary testiery > secondary> primary. - tertiary radical is highly substituted and being stabilised by the ti effect of three. a s Here ® has 7 hyper conjugative structure. * olao Here ® has a hyper conjugative structure. , 4 Cs Scanne On" | Scanned with CamScanner

so most stable is ® Boot Bad tereof is highly electronegetive atom, so it has - I effect greatly. As the distance of the radical will be greater the -I effect on that radical will be less prominent and will be stable. Here in the distance of radical from f is greater , so it is much more stable. i most stable ① A I Here Br is also electronegative, and has I effect. so according to above reasoning most stable will be oor radical. - allyliczalical allylic allylic radical can be delocalized, so would be more stable than ® & © ...
