In this reaction
ester is reduced to
aldehyde. Such reduction can not be achieved by reacting reducing agents like
LiAlH₄ because it will further reduce aldehydes to alcohols. So, in order to stop reduction at alddehyde, ester is reacted with bulky reducing agent, <span>
Diisobutylaluminium hydride (DIBAL) which works with same mechanism as that LiAlH</span>₄ do. It also add hydride to carbonyl group. The reaction is shown below,
Gas formation, precipitate formation, color change, temperature change, or odor
The answer is C, work. The reaction of the air/gas mixture being ignited produces energy which moves the piston up and down which turns the crankshaft.
Answer:
the anwser is; B: increasing its speed
