1.	Which of the following reaction will give alkyne ?
Answer» `CH_3underset(Cl)underset(\|)CH-underset(Cl)underset(\|)CH-CH_3 underset(H_3O^(+))overset(NaNH_2)to ` `CH_3CH_2 CHBr_2 underset((ii) NaNH_2)overset((i) ALC. KOH)to` `R-C -= CNA overset(R^(1)-X)to` Potassium maleate `overset("electrolysis")to` SOLUTION : Preparation of ALKYNES `{:(CHCOOK),(\|\|),(CHCOOK):} overset("Electrolysis")to {:(CH),(\|\|\|),(CH):} + 2CO_2 + 2KOH + H_2` `R-C -= CNa overset(R^(1)-X)to R -C -= C - R^(1) + NAX` `R-CHBr - CH_2Br - + 2NaNH_2 to R - C -= CH + 2NaBr`
