Consider the following addition reaction:

${\left({\mathrm{CH}}_3\right)}_2\mathrm{CHCH}={\mathrm{CH}}_2+\mathrm{HBr}\to$

Select incorrect statement about this reaction

Final product is ${\left({\mathrm{CH}}_3\right)}_2-{\mathrm{CBrCH}}_2{\mathrm{CH}}_3$

In presence of benzoyl peroxide final product is ${\left({\mathrm{CH}}_3\right)}_2{\mathrm{CHCH}}_2{\mathrm{CH}}_2\mathrm{Br}$

It follows electrophilic addition mechanism.

Most stable intermediate is the ${\left({\mathrm{CH}}_3\right)}_2\mathrm{CH}-\stackrel{+}{\mathrm{C}}{\mathrm{HCH}}_3$carbocation
