Write IUPAC name of CH 3 CH 2 C ( CH 3 ) 2 CH 2 I .

The given compound has the following structure. The longest chain contains four carbon atoms with iodo, methyl and another methyl groups at position 1 , 2 and 2 respectively. Therefore, the IUPAC name of the compound will be 1 - Iodo - 2 , 3 - dimethylbutane.

Identify ' Z ' in the following: C 6 H 5 Br → Mg / dry ether ' Z '

We have given, C 6 H 5 Br → Mg / dry ether ' Z ' When magnesium reacts with bromobenzene it forms phenyl magnesium bromide as shown below, C 6 H 5 Br → Mg / Dry ether C 6 H 5 MgBr

Predict the product in the following:

Carboxylic acids react with thionyl chloride to form acid chlorides. During the reaction the hydroxyl group of the carboxylic acid is converted to a chlorosulfite intermediate making it a better leaving group. The chloride anion produced during the reaction acts a nucleophile.

Predict the product in the following: CH 3 OH + PCl 5 →

The reaction of alcohols ROH with PCl 5 and PCl 3 yields an alkyl halide RCl . With PCl 5 , the reaction is quite simple leading to the formation of RCl and POCl 3 . CH 3 OH + PCl 5 → CH 3 Cl + POCl 3 + HCl

What happens when ethyl iodide reacts with alcoholic KOH solution?

When a halo alkane with β - hydrogen atom is heated with alcoholic solution of potassium hydroxide, there is elimination of hydrogen atom from β - carbon and a halogen atom from the α -carbon atom. As a result, an alkene is formed as a product. Since β - hydrogen atom is involved in elimination, it is often called β - elimination. So, when ethyl iodide reacts with alcoholic KOH solution it forms ethylene and the equation for this reaction is as shown below, CH 3 CH 2 I → Alc . KOH CH 2 = CH 2 + KI + H 2 O

Write IUPAC name of CH 3 C Cl C 2 H 5 CH 2 CH 3 .

The IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry. It is published in the Nomenclature of Organic Chemistry. We have give, CH 3 C Cl C 2 H 5 CH 2 CH 3 . IUPAC name of the given compound is 3 - Chloro - 3 - methylpentane, this is a tertiary 3 0 alkyl halide. The following is the structure of the given compound,
