Answer in Brief

Identify the α-carbon in the following species and give the total number of α-hydrogens.

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

Advertisements

Solution

\[\ce{\overset{1}{C}H2 = \overset{2}{C}H - \overset{3}{\underset{\alpha}{C}}H2 - \overset{4}{C}H3}\]

The C-3 carbon atom, that is, the C-atom next to \[\ce{(H2C = CH-)}\] is an α-C atom.

Thus, the structure contains 2 α-H atoms.
