Step by step solution

01

Definition of Lindlar’s catalyst and  H2,Pd/C

Lindlar’s catalyst – This catalyst only reduces the alkyne into alkene. This catalyst does not reduces alkene

H2,Pd/C - This catalyst reduces both alkyne and alkene converts into alkane.

02

Formation of product

Alkyne and alkene which are present in the compound has been reduced by H2,Pd/C

But Lindlar’s catalyst reduces only triple bond present in the compound.

Question: How could you use infrared spectroscopy to distinguish between the

following pairs of isomers?

(a)HC≡CCH2NH2andCH3CH2C≡N

(b)CH3COCH3andCH3CH2CHO


Beginning with acetylene and any alkyl halide needed, how would you synthesize the following compounds?

(a)Decane

(b)2,2-Dimethylhexane

(c)Hexanal

(d)2-Heptanone

Amino acids can be prepared by reaction of alkyl halides with diethyl acetamidomalonate, followed by heating the initial alkylation product with aqueous HCl. Show how you would prepare alanine, CH3CH(NH2)CO2H, one of the twenty amino acids found in proteins, and propose a mechanism for acid-catalyzed conversion of the initial alkylation product to the amino acid.
