The major product (s) obtained in the following reaction is/are:

First step of the reaction is dehydrohalogenation and then ozonolysis.

The dehydrohalogenation of alkyl halides, another ß elimination reaction, involves the loss of a hydrogen and a halide from an alkyl halide (RX). Dehydrohalogenation is normally accomplished by reacting the alkyl halide with a strong base, such as sodium ethoxide.
