Question:
The order of reactivity of the following compounds towards \( S_N2 \) displacement reaction is (i) 2-Bromo-2-methylbutane (ii) 1-Bromopentane (iii) 2-Bromopentane
The order of reactivity of the following compounds towards \( S_N2 \) displacement reaction is (i) 2-Bromo-2-methylbutane (ii) 1-Bromopentane (iii) 2-Bromopentane
Show Hint
Less steric hindrance $\Rightarrow$ faster \( S_N2 \).
