What is alkoxide group?

An alkoxide is the conjugate base of an alcohol and therefore consists of an organic group bonded to a negatively charged oxygen atom. They are written as RO−, where R is the organic substituent. Alkoxides are strong bases and, when R is not bulky, good nucleophiles and good ligands.

What is alkoxy and aryloxy group?

In chemistry, the alkoxy group is an alkyl (carbon and hydrogen chain) group singularly bonded to oxygen; thus R–O. An alkoxy or aryloxy group bonded to an alkyl or aryl (R1–O–R2) is an ether. If bonded to H it is an alcohol.

Why is alkoxide a good leaving group?

Oxygen donates a lone pair to the hydrogen of a hydronium ion (considering it to be in an aqueous solution). The water molecule now attached is a good leaving group (oxygen has a positive charge).

Is alkoxy a functional group?

Alkoxy is a functional group that has an oxygen atom bonded to an R group. This R group is referred to as an alkyl group. The molecular formula is R-O. Examples of chemicals containing alkoxy groups include methoxyethane and 3-isopropoxy-1-butanol.

What is meant by acyl group?

An acyl group is a moiety derived by the removal of one or more hydroxyl groups from an oxoacid, including inorganic acids. It contains a double-bonded oxygen atom and an alkyl group (R-C=O). In organic chemistry, the acyl group (IUPAC name: alkanoyl) is usually derived from a carboxylic acid.

Is OH a better leaving group than or?

The weaker the base the better the leaving group. Because OH – is a strong base, and Br– is a weak, Br– is a far, far, better leaving group. Here is why. A weak base is more stable then a strong base.

How is sodium alkoxide formed?

Sodium ethoxide can be obtained by reacting sodium hydroxide or sodium metal with ethanol. You can then remove the water by using a drying agent and you will obtain solid sodium ethoxide, that is yellow.
