LiAlH₄ is used as strong reducing agent. The hydride produced acts as a nucleophile and attacks the electrophillic carbon of carbonyl group. In given example two reactions are observed.
Reaction 1: In first step LiAlH₄ when treated with
Ester produces corresponding
Aldehyde and alcohol.
Reaction 2: This aldehyde produced further reacts with LiAlH₄ to give a reduced product (
Alcohols). In this case Butanol is produced.
The reaction schemes are shown as felow,
Dimitry Mendeleef
Explanation:
Dimitry Mendeleef developed a table of elements which revealed regularities in elemental properties. He discovered the periodic arrangement of elements in 1869 while playing his game of solitaire.
- John Newlands in in 1863 proposed the idea of a repeating octaves of properties of elements.
- Dimitry Mendeleef described the periodic table or chart in 1869
- The chart was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
- In his periodic table, elements were arranged by atomic weights with recurring properties in a periodic manner>
