Chemistry - ALCOHOL & ETHER Question with Solution | TestHub

Alkyl halide is $1^{\circ }$. Keep in mind $1^{\circ }$ halide give product by ${\mathrm{S}}_{\mathrm{N}}2/\mathrm{E}-2$ mechanism and $1^{\circ }$ halide always gives substitution reaction except when strongly hindered base is used. e.g., with
$$\text{ it gives mainly elimination. }$$ $$\text{ The reaction involves carbocation intermediate. }$$ i.e.
but as it is a primary carbocation it will rearrange to give a tertiary carbocation, which completes the reaction
Stability of carbocation : $3^{\circ }>2^{\circ }>1^{\circ }>\stackrel{\oplus }{{\mathrm{CH}}_3}$ It is because the stability of a charged system is increased by dispersal of the charge. The more stable the carbocation, the faster it is formed. N.B. - Rearrangement can be done in two ways.
