Detection of Functional Groups (Theory) : Organic

Systematically identify the functional groups in the given organic compound and perform the confirmatory tests after identifying the functional groups Reactions of amides: Reaction of NaOH: Amides are decomposed by NaOH to evolve ammonia The gas can be tested by a moist red litmus paper which is then turned blue Alkaline hydrolysis of aromatic amides to aromatic acid: The soluble sodium

Organic Chemistry: Stereoisomers: Racemic Mixtures and

A solution in which both enantiomers of a compound are present in equal amounts is called a racemic mixture or racemate Racemic mixtures can be symbolized by a (d/l)- or ()- prefix in front of the substance's name Since enantiomers have equal and opposite specific rotations a racemic mixture

Substitution Reaction: Definition Types and Applications

1 Nucleophilic Substitution When electron-rich species (nucleophile) provides an electron pair for bonding with the compound being transformed it is called nucleophilic substitution Some examples of nucleophiles are Cl – Br – I – OH – RO – CN – H 2 O and NH 3 Types of Nucleophilic Substitution:

Types of Alcohols

Alcohols are those organic compounds which are characterized by the presence of one two or more hydroxyl groups (−OH) that are attached to the carbon atom in an alkyl group or hydrocarbon chain These alcohols are considered to be as the derivatives of water where one among the hydrogen atoms are replaced by alkyl group which is typically represented by the letter R in an organic structure

Chiral synthesis BOC Sciences

Chiral pool synthesis is especially attractive if your target molecules having similar chirality to a relatively inexpensive naturally occurring building-block such as a sugar or amino acid BOC Sciences has the function of sourcing such chiral raw materials at competitive and reasonable cost through our overseas network Our scientists are well trained to evaluate the project and find the

Esters

Esters are an important functional group in organic chemistry and they are generally written RCOOR' or RCO 2 R' Esters An ester is characterized by the orientation and bonding of the atoms shown where R and R' are both carbon-initiated chains of varying length also known as alkyl groups As usual R and R' are both alkyl groups or groups initiating with carbon
