Identify the α - carbons in the following species and give the total number of α-hydrogen.

\[\ce{CH3 - CH2 - \overset{⊕}{C}H - CH2 - CH3}\]

Identify the α-carbons in the following species and give the total number of α-hydrogen.

\[\ce{CH2 = CH - CH2 - CH3}\]

Shravani was performing inorganic qualitative analysis of a salt. To an aqueous solution of that salt, she added silver nitrate. When a white precipitate was formed. On adding ammonium hydroxide to this, she obtained a clear solution. Comment on her observations and write the chemical reactions involved.
