Explanation:

Bronsted acids are the species which donate protons.

In the given species, we can see that fluorine is the most electronegative atom hence, [tex]H_{2}F^{+}[/tex] will not give proton easily. Therefore, its acidity will be the least.

Similarly, sulfur is also electronegative but less electronegative than fluorine atom. Hence, acidity of [tex]CH_{3}SH_{2}^{+}[/tex] is slightly more than [tex]H_{2}F^{+}[/tex].

Whereas [tex]CH_{3}OH[/tex] will have highest bronsted acidity and [tex](CH_{3})_{2}OH^{+}[/tex] will be less acidic than [tex]CH_{3}OH[/tex].

Thus, we can conclude that order of increasing bronsted acidity is as follows.

      [tex]H_{2}F^{+}[/tex] < [tex]CH_{3}SH_{2}^{+}[/tex] < [tex](CH_{3})_{2}OH^{+}[/tex] < [tex]CH_{3}OH[/tex]
