MCQ
Which is most acidic of the following
  • A
    Methane
  • ✓
    Acetylene
  • C
    $1-$butene
  • D
    Neo-pentane
✓

Answer

Correct option: B.
Acetylene
b
(b)The $s-$ character of $C - H$ bond of acetylene is higher in comparison to $C - H$ bond of ethene and ethane. The electrons of the $C - H$ bond in acetylene are strongly held by carbon nuclei. This facilitates the removal of hydrogen as proton.
