The test for the presence of Ag⁺ in an unknown solution involves the treatment of the silver–ammonia complex with dilute hydrochloric acid. The appearance of a white precipitate at this point indicates the presence of silver ion in the original sample. The net ionic equation that represents this test is __

Ag(NH₃)₄⁺ + 4 HCl → AgCl_(s) + 4 NH₄⁺ + 3 Cl⁻

Ag(NH₄)₄⁺ + Cl⁻ → AgCl_(s) + 4 NH₄⁺

Ag(NH₃)₂⁺ + Cl⁻ → Ag(NH₃)₂Cl_(s)

Ag(NH₄)₄⁺ + 4 H⁺ → Ag_(s) + 4 NH₄⁺

Which of the following statements about cis-trans isomers is not correct?

In the cis- isomer, the groups of interest are on the same side of the double bond

Conversion between cis- and trans-isomers occurs by rotation around the double bond

In the trans- isomer, the groups of interest are on opposite sides across the double bond

There are no cis-trans isomers in alkynes
