WebCorrect option is A) According to the structure, the carbon numbered as 1, in, 1-butyne has hydrogen attached to it. This carbon atom is ‘sp’ hybridized, which means it has a higher s character that means higher electronegativity, therefore, the tendency to donate the H+ ion will be higher in 1-butyne. Hence i-butyne has one 1 acidic hydrogen. WebButyne -1 having acidic hydrogen gives silver acetylide precipitate, butene-1 has no acidic hydrogen ,hence, does not give a precipitate due to absence of acidic hydrogen. truckers ottawa airport
