Question

The correct order for acid strength of compounds :
CH ≡ CH, CH₃ – C ≡ CH, CH₂ = CH₂
is as follows:
(A) CH ≡ CH > CH₂ = CH₂ > CH₃ – C ≡ CH
(B) CH₃ – C ≡ CH > CH ≡ CH > CH₂ = CH₂
(C) CH₃ – C ≡ CH > CH₂ = CH₂ > HC ≡ CH
(D) HC ≡ CH > CH₃ – C ≡ CH > CH₂ = CH₂

Answer 1

Explanation:

CH≡ CH > CH3 - C ≡ CH > CH2 = CH2 (Acidic strength order).More is the s - character, more is the acidic strength.

Answer 2

Answer:option 4

Explanation:

because triple bond having adjacenthydrogen atoms are more acidic than double bonded ones
