1.	(i) An organic compound (A) of a molecular formula C_(2)H_(4) which is a simple allllllklene. A reacts with dil H_(2)SO_(4) to give B. A again reacts with Cl_(2) to give C. A,B and C and write the equations. (ii) Why chloro acetic acid is stronger acid than acetic acid?
Answer» Solution :(B) (i) 1 `C_(2)H_(4) " is " CH_(2)=CH_(2)` is a simple ALKENE. A is ethylene. 2. Ethylene (A) reacts with dil `H_(2)SO_(4)` to give ethanol (B) `UNDERSET("Ethylene" (A))(CH_(2)CH_(2)) overset(dil H_(2)SO_(4))rarr CH_(3) - underset("ethanol"(B))(CH_(2) - OH)` 3. Ethylene (A) reacts with `Cl_(2)` to GIVEN 1,2 dichloro ethane (C) `underset(underset(A)(("Ethylene")))(CH_(2) = CH_(2)) overset(Cl_(2))rarr underset(("1,2-dichloro ethene)(C)"))(underset(underset(Cl)(\|))(CH_(2)) - underset(underset(Cl)(\|))(CH_(2)))` (ii) Chloro acetic acid: `Cl larr CH_(2) larr overset(overset(O)(\|\|))(C) larr O larr H` Chloro acetic acid has Cl-group and it has high electronegatively and shown -I effect. Therefore Cl-atom to facilitate the dissociation of O-H bond very fastly. Whereas in the case of acetic acid, has `CH_(3)` group and it showns + I effect, therefore dissociation of O-H bond will be more difficult. Thus chloro acetic acid is STRONGER acid than acetic acid.
