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 44 u. Write IUPAC name of ‘A’.

Explanation

The aldehyde having molar mass 44 u is ethanal, `CH_3CHO` . Since, the alkene A on ozonolysis gives two moles of ethanal, `(CH_3 - undersetoverset(|)(H)(C) = O)` , its structure can be obtained by removing O atoms from two molecules of ethanal and joining them together by a double bond. Thus, the alkene A has the following structure :
As shown above, but-2-ene has three C-C, eight C-H o-bonds and one C-C `pi`- bond.
