Identify the alkyne in the following sequence of reactions,
A.
In Wacker process, alkene is oxidised into aldehyde.
Since on ozonolysis, only alkenes produce aldehydes, 'A' must be an alkene. To decide the structure of alkene that undergoes ozonolysis, bring the products together in such a way that O atoms are face to face and, replace O by double (=) bond. Thus,
