Base strength of (i)H_(2)Coverset(oplus)CH_(2) (ii) H_(2)C = oplus(CH)

1.	Base strength of (i)H_(2)Coverset(oplus)CH_(2) (ii) H_(2)C = oplus(CH) and (iii) H- C -= C^(oplus) is in the order of
Answer» `(ii) gt (i) gt (III)` `(iii) gt (ii) gt (i)` `(i) gt (iii) gt (ii)` `(i) gt (ii) gt (iii)` SOLUTION :Acidic `HC -= CH gt CH_(2) = CH_(2) gt CH_(3) - CH_(3)` ELECTRONEGATIVITY `SP gt SP^(2) gt SP^(3)`
