Identify the α-carbons in the following species and give the total number of α-hydrogen.
\[\ce{CH_3 - CH_2 - \overset{⊕}{C}H-CH_2 - CH_3}\]
उत्तर
\[\ce{\overset{5}{C}H3 - \underset{\alpha}{\overset{4}{C}}H2 - \underset{+}{\overset{3}{C}}H - \underset{\alpha}{\overset{2}{C}}H2 - \overset{1}{C}H3}\]
In structure, C-2 and C-4 are α-carbon atoms.
Hydrogen atoms(s) attached to α-C atoms is an α-H atom. Thus, the structure contains 4 α-H atoms.
