Question

Electron withdrawing groups examples in increasing order

Answer 1

Answer:

Explanation:

Inductive effect (I effect): displacement of sigma electrons along a saturated carbon chain when an electron donating (+I effect) or electron withdrawing (-I effect) group is attached at the end of the carbon chain.

Decreasing order of -I effect : R3N- > -NO2 > -SO2R > -CN > -COOH> -F> -Cl > -Br > -I > -OR > -COR > -OH > - C6H5 > -CH=CH2 > -H

Decreasing order of +I effect : (CH3)3C- > (CH3)2CH- > CH3CH2– CH3- > -H
