Question

Among the choices of alkyl bromide, the least reactive bromide in SN2 reaction is (A) 1 -bromopentane (B) 2-bromo-2-methylbutane (C) 1-bromo-3-methylbutane (D) 1 -bromo-2-methylbutane

The reactivity of different alkyl halides towards

S_{N} 2

reaction decreases in the order:
methyl halides

> 1^{\circ}

halides

> 2^{\circ}

halides

> 3^{\circ}

halides.
Since,

2

-bromo-

2

-methylbutane is a tertiary bromide hence it is least reactive among the given

Q. Among the choices of alkyl bromide, the least reactive bromide in SN​2 reaction is

1 -bromopentane

2-bromo-2-methylbutane

1-bromo-3-methylbutane

1 -bromo-2-methylbutane

The reactivity of different alkyl halides towards SN​2 reaction decreases in the order: methyl halides >1∘ halides >2∘ halides >3∘ halides. Since, 2-bromo-2-methylbutane is a tertiary bromide hence it is least reactive among the given

Q. Among the choices of alkyl bromide, the least reactive bromide in $S_{N} 2$ reaction is

The reactivity of different alkyl halides towards $S_{N} 2$ reaction decreases in the order:
methyl halides $> 1^{\circ}$ halides $> 2^{\circ}$ halides $> 3^{\circ}$ halides.
Since, $2$ -bromo- $2$ -methylbutane is a tertiary bromide hence it is least reactive among the given
