Arrange the following in increasing order of their `pK_(a)` values.
(x) `CH_(3)-underset(O)underset(||)overset(O)overset(||)S-O-H`
(y) `CH_(3)-overset(O)overset(||)C-O-H`
(z) `CH_(3)-OH`

A

`yltxltz`

B

`xltyltz`

C

`yltzltx`

D

`xgtzgty`

Text Solution

Verified by Experts

The correct Answer is:
B
Stability of reaction hybrid `prop` no. of equivalent R.S So stability order is
`Me-underset(3-eq.R.S)underset(O)underset(||)overset(O)overset(||)S-O^(Ө)gtMeunderset(2-eq.R.S)overset(O)overset(||)C-O^(Ө)gtMe-O^(Ө)`
So Acidic, strenght order is `xgttgtz` so `pK_(a)` is `zgtygtx`
