Solution and Explanation
(i) Pent-2-ene undergoes ozonolysis as:
The IUPAC name of Product (I) is ethanal and Product (II) is propanal.
(ii) 3, 4-Dimethylhept-3-ene undergoes ozonolysis as:
The IUPAC name of Product (I) is butan-2-one and Product (II) is Pentan-2-one.
(iii) 2-Ethylbut-1-ene undergoes ozonolysis as:
The IUPAC name of Product (I) is pentan-3-one and Product (II) is methanal.
(iv) 1-Phenylbut-1-ene undergoes ozonolysis as:
The IUPAC name of Product (I) is benzaldehyde and Product (II) is propanal.
Top Questions on Alkenes

Alkenes
In organic chemistry, an alkene is a hydrocarbon containing a carbon-carbon double bond.[1]
Alkene is often used as synonym of olefin, that is, any hydrocarbon containing one or more double bonds.

IUPAC Nomenclature of Alkenes
- An alkene or cycloalkene is indicated by the suffix (ending) ene.
- For the root name, the longest chain must include both carbon atoms of the double bond.
- The root chain must be numbered beginning at the end closest to a double bond carbon atom. If the double bond is in the chain's centre, the nearest substituent rule is used to determine where the numbering begins.
- If the compound contains more than one double bond, it is named with a diene, triene, or equivalent prefix indicating the number of double bonds, and each double bond is assigned a locator number.
