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

An aldehyde having molecular mass of 44 a.m.u. is ethanal, `CH_(3)CHO`
It gives two moles of ethanal
`CH_(3)CH=O O= CH-CH_(3)`
Alkene is `CH_(3)CH= CH-CH_(3)` or `H- underset(H)underset(|)overset(H)overset(|)C-overset(H)overset(|)C=overset(H)overset(|)C-underset(H)underset(|)overset(H)overset(|)C-H`
But-2-ene has three C-C o bonds, one C—C pi bond and eight C-H o bonds.
