Current Question (ID: 21263)

Question:

$\text{Given the following benzyl/allyl system:}$ $\text{R} - \text{C} = \text{CH}_2 \quad \text{or} \quad \begin{array}{c} \text{R} \\ \bigcirc \\ \end{array}$ $\text{(R is alkyl group)}$ $\text{What is the correct decreasing order of the inductive effect?}$

Options:

1. $(\text{CH}_3)_3\text{C}- > (\text{CH}_3)_2\text{CH}- > \text{CH}_3\text{CH}_2-$
2. $\text{CH}_3\text{CH}_2- > (\text{CH}_3)_2\text{CH}- > (\text{CH}_3)_3\text{C}-$
3. $(\text{CH}_3)_2\text{CH}- > \text{CH}_3\text{CH}_2- > (\text{CH}_3)_3\text{C}-$
4. $(\text{CH}_3)_3\text{C}- > \text{CH}_3\text{CH}_2- > (\text{CH}_3)_2\text{CH}-$

Solution:

$\text{Hint: As number of carbon atom increases in the group the inductive effect also increases.}$ $\text{As number of carbon increases the inductive effect of alkyl group also increase.}$ $\text{The tertiary carbon show more inductive effect than secondary carbon and secondary carbon shows more inductive effect than primary carbon.}$ $\text{Hence, the correct order is } (\text{CH}_3)_3\text{C}- > (\text{CH}_3)_2\text{CH}- > \text{CH}_3\text{CH}_2-.$
