1.	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’.
Answer» Solution : 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.
