A hydrocarbon A, of C_8H_10, on ozonolysis gives compound (B), C_4H_6O_2 only. The compound (B) can also be obtained from alkyl bromide (C), C_3H_5Br, upon treatment with magnesium in dry ehter, followed by CO_2 and acidification. Identify (A), (B) and (C) and aslo give equations for the reactions.

Answer» <html><body><p></p>Solution :The compound (B) is formed via the formation of <a href="https://interviewquestions.tuteehub.com/tag/grignard-477224" style="font-weight:bold;" target="_blank" title="Click to know more about GRIGNARD">GRIGNARD</a> reagent followed by reaction with `CO_2` and <a href="https://interviewquestions.tuteehub.com/tag/acidification-366955" style="font-weight:bold;" target="_blank" title="Click to know more about ACIDIFICATION">ACIDIFICATION</a>. It shows that `C_3H_5Br` behaves like <a href="https://interviewquestions.tuteehub.com/tag/saturated-3007745" style="font-weight:bold;" target="_blank" title="Click to know more about SATURATED">SATURATED</a> compound. It is only <a href="https://interviewquestions.tuteehub.com/tag/possible-592355" style="font-weight:bold;" target="_blank" title="Click to know more about POSSIBLE">POSSIBLE</a> if `C_3H_5Br` is bromocyclopropane (Cyclopropylbromide). <br/> <img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/GRB_ORG_CHM_P2_S01_C17_006_S01.png" width="80%"/> <br/> (A) on ozonolysis <a href="https://interviewquestions.tuteehub.com/tag/gives-1007647" style="font-weight:bold;" target="_blank" title="Click to know more about GIVES">GIVES</a> only (B), hence it should be symmetrical unsaturated hydrocarbon. <br/> <img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/GRB_ORG_CHM_P2_S01_C17_006_S02.png" width="80%"/></body></html>
