PLEASE EXPLAIN THANK YOU

2. Rank the following acids (underlined H) from most acidic-to-least acidic. [Note: 1 > 2 > 3 indicates that 1 is the most acidic and 3 is the least acidic.] a)1 > 2 > 3 b)1 > 3 > 2 c)2 > 1 > 3 d)2 > 3 > 1 e)3 > 1 > 2 f)3 > 2 > 1

Answer 1

the correct option is :-

f) 3 > 2> 1

This is because compounds having sp hybrid orbital have more acidic character than compounds havind sp² & sp³ hybrid orbitals as greater the 's' charater in the hybrid orbitals, more will be the acidity.

Answer 2

answer is e. 3>2>1.

Reason:

if the carbon carrying hydrogen have more s character that hydrogen is more acidic. more s character means the nucleus has more electro negative nature hence its acidity is more.

in 3, alkyne carbon carrying hydrogen is more acidic due to the sp hybridisation of alkynic carbon.

second is 2, which has alkene carbon. this has sp2 hybridisation. so s character is less. third one is alkene which have sp3 hybridisation.

Answer 3

F) 3>2>1
