    1st is most acidic...as sp hybridization..50% s character...so electronegativity is more here

    eduncle-logo-app

    IV is least acidic...as here +I effect of methyl group decreases the acidity

    hope you got this

    eduncle-logo-app

    here in 1st str, there is sp hybridised Carbon make is most acidic

    eduncle-logo-app

    while in 2nd structure there is sp2 C so it is less acidic than 1st

    eduncle-logo-app

    3rd have benzene ring which show +R effect make the acidic Carbon more electron dense but it also have -I effect of ring so overall less acidic than 1st and 2nd

    eduncle-logo-app

    iv is least acidic because of +I effect

    eduncle-logo-app

    Got it?
