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

(i) `underset("Pent-2-ene")(CH_(3)-CH_(2)-CH)=CH-CH_(3) underset((ii)ZnH_(2)O)overset((i)O_(3)CH_(2)Cl_(2))to underset("Propanal")(CH_(3)- CH_(2)- CHO)+ underset("Ethanal")(CH_(3)-CHO)`
(ii) `CH_(3)-CH_(2)-CH_(2)-underset("3,4-Dimethylhept-3-ene")(underset(CH_(3))underset(|)C=underset(CH_(3))underset(|)C)-CH_(2)-CH_(3) overset("Ozonolysis")to CH_(3)CH_(2)CH_(2)-underset("Pentan-2-one")(underset(CH_(3))underset(|)C)=O+O=underset("Butan-2-one")underset(CH_(3))underset(|)C-CH_(2)CH_(3)`
