    EWG increase the acidity of carboxylic acid while ERG decrease the acidity. here akene and alkyne have - I effect. alkyne have more -I than alken so IV>III in case of alkyl alkyl groups, it decreases the Acidity. more the number of carbons more is the +I and less is the Acidity. so II>I overall IV>III>II>I
