Question

What is the correct major Organic product for the following transformation? 1. Mg 2. CO2 Y Br 3. H30+, heat

Answer 1

BO 2.Co2 3. H₂8, heat m oH+ Mg Brou * James from Highest to lowest Note : As the number of conjugated pi bonds increases, the Jo man increases as well. the correct order of amax is as follows. E>> B> DA Anide

Explantion :

Ans 1) Mg metal forms grignard reagent when reacts with bromo compound which upon reaction with CO2 followed by acidic work up gives acid as amajor product.

Ans 2) Alkene reacts with Ozone and Zn/H2O gives the ketone product.

Ans 3) The correct order is E>C>B>D>A

As the number of conjugated pi bonds increases, the λmax increases as well! Because longer frequency = smaller energy, this means that the energy gap ΔE between the highest-occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) decreases as the number of conjugated pi bonds increases.

Ans 4) When acid chloride reacts with amine gives amide product.
