Q. Which of the following has most acidic proton :

$C H_{3} COC H_{3}$

$(C H_{3})_{2} C = C H_{2}$

$C H_{3} COC H_{2} COC H_{3}$

$(C H_{3} C H)_{3} C H$ .

(Aceto ester) contains two electron withdrawing groups around $C H_{2}$ and this $C H_{2}$ group is called active methylene group and its hydrogens are acidic.

Q. Which of the following has most acidic proton :

CH3​COCH3​

(CH3​)2​C=CH2​

CH3​COCH2​COCH3​

(CH3​CH)3​CH.

(Aceto ester) contains two electron withdrawing groups around CH2​ and this CH2​ group is called active methylene group and its hydrogens are acidic.

$C H_{3} COC H_{3}$

$(C H_{3})_{2} C = C H_{2}$

$C H_{3} COC H_{2} COC H_{3}$

$(C H_{3} C H)_{3} C H$ .

(Aceto ester) contains two electron withdrawing groups around $C H_{2}$ and this $C H_{2}$ group is called active methylene group and its hydrogens are acidic.
