Choose the most appropriate reagent(s) for the conversion of propyne and 2-methyl-1-tosyloxypropane to 5-methyl-2-hexyne. nanh2, nh3 naoh, h2o koch2ch3, hoch2ch3 h2so4 nh3

NaNH2, NH3

Explanation:

Choose the most appropriate reagent(s) for the conversion of propyne and 2-methyl-1-tosyloxy propane to 5-methyl-2-hexyne. NaNH2, NH3 NaOH, H2O KOCH2CH3, HOCH2CH3 H2SO4 NH3

answer is  NaNH2, NH3

NaNH2, NH3 is strong to to convert propyne into a nucleophilic salt which in turn displaced tosylate in  2-methyl-1-tosyloxy propane to yield  5-methyl-2-hexyne.

Propyne and 5-methyl-2-hexyne. are still of the same homologous series,, so no triple bond is broken during the reaction

The essence of a reagent is to bring the reaction to its end point

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
