An alkene ‘A’ contains three C – C, eight C – H σ bonds and one C – C π bond. ‘A’ on ozonolysis gives two moles of an aldehyde of molar mass 44 u. Write IUPAC name of ‘A’.

Question

Philoid · Accepted Answer

According to the question alkene ‘A’ on ozonolysis gives two moles of an aldehyde having a molar mass 44 u. The formation of two moles of an aldehyde indicates the presence of identical structural units on both sides of the double bond-containing carbon atoms. Hence, the structure of ‘A’ can be represented as:-

XC = CX

There are eight C–H σ bonds. Hence, there are 8 hydrogen atoms in ‘A’. Also, there are three C–C bonds. Hence, there are four carbon atoms present in the structure of ‘A’.

Combining the inferences drawn above, the structure of ‘A’ can be represented as:

But-2-ene

Ozonolysis of ‘A’ takes place in the following manner:-

The final product is ethanal with molecular mass 44u.
