If a mixture containing ethyl acetate and Ethyl propanoate is refluxed. With `C_2 H_5 O Na // C_2 H_5 OH` ester condensation takes place. How many different condensation products would be formed.

If 3-chloromethylhexane is treated with C_(2)H_(5)Ona//C_(2)H_(5)OH, E_(2) elimination reaction takes place predominantly. How many different alkenes would be formed ?

Ethyl acetate on treatment with ethoxide ions (NaOC_(2)H_(5)) produces

(a) Give the Claisen ester condensation product of ethyl butanoate. (b) Why does the Claisen ester condensation of ethyl-2-methyl propanoate (I) not take place ? ( c) Why does Claisen condensation of (I) take place by the use of Ph_3 C^(Ө) Na^(oplus) as a base ?

Redution of ester with Na //C_(2)H_(5)OH is called as :
