Question

Encircle the weaker base between the two. Explain $$why.HSe^{− }or$$ $$HS^{−}$$

Accepted Answer

$$HSe^{−}$$;Its corresponding acid ($$H_{2}Se) $$has a longer and weaker bond to H, making it a stronger acid and its conjugate base $$(HSe^{−}) a $$weaker base.

Answer

$$HS^{−}$$;Its corresponding acid ($$H_{2}S) $$has a longer and weaker bond to H, making it a stronger acid and its conjugate base $$(HS^{−}) a $$weaker base.

Answer

Neither of the two;The two conjugate bases are similar in strength since the central atoms belong to the same group.

Answer

Neither of the two;The two conjugate bases are similar in strength since the central atoms have very close radii and electronegativities.
