Write IUPAC names of the products obtained by the ozonolysis of the following compounds:
(i) Pent-2-ene (ii) 3,4-Dimethyl-hept-3-ene
(iii) 2-Ethylbut-1-ene (iv) 1-Phenylbut-1-ene

Explanation

3, 4-dimethylhept-3-ene on ozonolysis gives two ketones, Butan-2-one and Pentan-2-one
`underset("3,4-dimethylhept-3-ene")(CH_(3)-CH_(2)- underset(underset(CH_(3))(|))(C )underset(underset(|)("|"))overset(overset(|)("|"))(=)underset(underset(CH_(3))(|))(C ))- CH_(2)CH_(2)CH_(3) underset(Zn//H_(2)O)overset(O_(3))rarr CH_(3)- underset(underset(H)(|))(C )= O`
`underset("Butan-2-one")(CH_(3)-CH_(2)-underset(underset(CH_(3))(|))(C )= O) + underset("Pentan-2-one")(CH_(3)-CH_(2)- CH_(2)- underset(underset(CH_(3))(|))(C )= O)`
