Solution
The correct option is D ii > i > iv > iii Permanent shift in electron density away from the carbon chain to the substituent is called -I effect. -I group leads to development of ẟ+ on C atom sharing a bond with the substituent. Electron withdrawing groups show negative inductive effect. Electron withdrawing groups means substituent which withdraws electron pair towards itself. So the correct order will be
