ABC CLASSES FOR IIT-JEE

ALKYL HALIDE & ORGANOMETALLIC COMP.

D.P.P. - 1

1. State whether statement is true or false. & Give explanation.

Aryl halides are more reactive than alkyl halides towards nuclophellic reagents .

2. Predict the major products.

(i) ?CHCOCHHCH.2

MgBrCH.132256

3 → + (ii)

(iii) 33?MgBrCH

3 CH

OH|

H|CCH?CHOCH 3 −−→ →−

3. Propose a mechanism for the following reactions.

4. Write the organic product.

5. Predict the products: - PhMgBr + PhOCH2CN ?

6. An organic compound (A). C4H9Cl on reacting with aqueous KOH gives (B) and on reacn with alc.

KOH gives (C) which is also formed by passing vapour of (B) over heated copper. The compound

(C) readily decolourises Br2 water. Ozonolysis of (C) gives two compounds (D) and (E). Compound

(D) reacts with NH2OH to give. (F) and the compound (E) reacts with NaOH to give on alcohol (G)

and sodium salt (H) of an acid (D) can also be prepared from propyne on treatment with water in

presence of Hg2+ and H2SO4. Identify A to H.

7. Account for the rapid rati of ethanolysis of ClCH2OCH2CH3, although the substrate as a 10 halide.

8. The reaction of 10 alkyl halide with nitrite salts produces both KNO2 + KONO. Explain why?

9.

Identify B to F.

10. Identify A to E.
