Question

Enter the chemical formula of a binary molecular compound of hydrogen and a Group 4A element that can reasonably be expected to be more acidic in aqueous solution than , e.g. have a larger .

Answer 1

Answer: GeH4 (Germanium(IV) Hydride)

Explanation:

A Binary molecular compound Hydrogen and a Group 4A element which is more more acidic than SiH4 in aqueous solution is GeH4.

The pKa of GeH4;

= 25

Whilst that of SiH4

= 35

The lesser the pKa the higher the Ka which means more acidic.
