Ozonolysis of 2,5-dimethyl-2,4-hexadiene gives a total number of carbonyl compounds equal to .

Answer: 3

Solution

2,5-Dimethylhexa-2,4-diene is CH3−C(CH3)=CH−CH=C(CH3)−CH3, with double bonds at C2=C3 and C4=C5. Ozonolysis cleaves each C=C bond, converting each alkene carbon into a carbonyl carbon. Cleaving C2=C3 converts C2 (bearing two methyl groups, C1 and the 2-methyl substituent) into (CH3)2C=O, acetone. Cleaving C4=C5
