Answer 1

the Iupac name of A is 2-methyl 1-phenylbutene.

Answer 2

Answer:The structure of A: 2-methyl-1-phenyl-But-1-ene

Explanation:

The ozonolysis of alkene result in cleavage of double bond and reductive ozonolysis with Zinc and water results in formation pod carbonyl compounds(aldehydes , ketones)

$A+O_3\overset{Zn/H_2O}\rightarrow$ Benzaldehyde + Butan-2-one
