Draw the final product obtained when one molecule of disiamylborane is reacted with 3-methylbut-1-yne and then hydrogen peroxide and sodium hydroxide solution are added.

Here we have to draw the structure of the final product obtained from the reaction between disiamylborane with 3-methyl-but-1-yne and successive addition of H₂O₂ and NaOH.

The final product of this reaction is 3-methyl butanal

The disiamylborane is a selective reagent to form the aldehyde from the alkyne. The final product in this reaction will be 3-methyl butanal which is shown in the figure.

In the first step of the reaction the boron atom attached with the terminal carbon of the given molecule and in the next step on addition hydrogen peroxide and sodium hydroxide the reduced oxidation happen to form the corresponding aldehyde.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
