Question

For the compounds $HF,HBr,H_{2}Se,H_{2}Te,H_{3}P$ which of the following statement is true?

• A. $HF$ (strong acid)
• B. $H_{2}Te$ (strong base)
• C. $HBr$ (strong acid)
• D. $H_{3}P$ (strong base)

Answer 1

Answer: (B), (C)

The correct options are
B $H_{2}Te$ (strong base)
C $HBr$ (strong acid)

Among these compounds, $HBr$ is comparatively strong acid, $HF$ is weak acid, $HBr$ is strong acid due to weak covalent bonding and strong ionic bond.$H_{2}Te$ is a strong acid not a strong base.$H_{3}P$ is also a amphoteric in character.
