The correct order of acidity among the following is:
1. CH2=CH2 >CH≡CH > CH3C≡CH > CH3-CH3
2. CH≡CH > CH3-C≡CH > CH2=CH2 >CH3-CH3
3. CH≡CH > CH2=CH2 > CH3-C≡CH > CH3-CH3
4. CH3-CH3 > CH2=CH2 > CH3-C≡CH > CH≡CH
The correct order of strengths of the carboxylic acids :-
(a) I>II>III
(b) II>III>I
(c) III>II>I
(d) lI>I>IlI
