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,
The correct answer is B. it measures the tendency of a radioisotope to decay radioactively.
B is the answer. It is the steepest
<span>because if there is the same amount of atoms on the reactants and the products obviously none is lost :)</span>
