An alkene 'A' contains three C-C, eight C-H `sigma` bonds and one C-C `pi`- bond . 'A' on ozonolysis gives two moles of an aldehyde of molar mass 44u. Write IUPAC name of 'A'.

Explanation

An aldehyde with molar mass 44u is ethanal `(CH_(3)CH =O)`. Formuls of the alkene 'A' which on ozonolysis gives two moles of ethanal can be determined as follows-
`underset("Eithanal")(CH_(3)CH) = O + O = underset("Ethanal")(CHCH_(3)) rarr CH_(3) - underset("But-2-ene(A)")(CH = CH) - CH_(3)`
There are three `C -C sigma`-bonds, eight `C-H " "sigma`-bonds and one `C-C pi`-bond in but -2-ene
