Given, An Alkene contains
-three C-C bonds,
-eight C-H , sigma bonds ,
-one C - C , π bond,

also given , 'A' on Ozonolysis gives two moles of an aldehyde of molar mass 44u .
it means Aldehyde must be ethanol (CH3CH=O) [ because molar mass of ethanal is 44u]

now, we have to write two moles of ethanal side by side with their oxygen atoms pointing towards each other, remove the oxygen atoms and join them by a double bond, the structure of Alkene 'A' is But-2-ene .

As required , but-2-ene has three C-C atoms , eight C-H, sigma bonds and one C-C , π bond.

Answer:

Answer

The aldehyde with molar mass of 44 u is acetaldehyde. 2 molecules of acetaldehyde are obtained on ozonolysis. Hence, the alkene A is But - 2 - ene.

It contains three C-C σ bonds, eight c−H σ bonds and one c=c π bond.
