Textbook Problem

(a) Draw the structure of the compound obtained from the reaction of HBr with ethylene, and name the compound.

(b) Draw the structure of the product of the reaction of Br2 with cis-2-butene, and name this compound.

(a)

Interpretation Introduction

Interpretation:

The structure of the compound obtained from the reaction of HBr with ethylene has to be drawn and named.

Concept introduction:

Systematic Name: It is a standardized name given for a chemical compound in systematic manner. Any organic molecule can be named by using IUPAC (International Union for Pure and applied chemistry) rules. IUPAC name consists of three parts in major namely Prefix suffix and root word.

IUPAC naming for Alkane:

Name the main chain: Find the longest carbon chain and name the chain according to the number of carbon atoms it contains; is also the suffix part of the name.

Number the carbon atoms in the main chain: The carbons are numbered, in which the substituents must get lowest possible numbers.

Identify the substituents, and number each: The number at where substituents are present has to be noted. The substituents written as prefix.

Write the names as a single word: Use the hyphen to separate the numbers from the different prefix; commas to separate numbers. If two or more different substituents are present, arrange them in alphabetical order. If two or more identical substituents are present, use prefixes di-, tri-, tetra-, but this particular prefix should not be used for alphabetizing purpose.

Alkenes are the hydrocarbons which have a genral molecular formula CnH2n. Alkenes are consist of double bond (one pi bond) due to which they are known as unsaturated hydrocarbons.

The systematic name has -ene in the suffix of the parent name of the longest carbon atoms chain.

Explanation

Ethylene reacts with hydrogen bromide to form Bromo ethane. Here H+ from hydrogen bromide attacks the ethylene to form a carbocation. This carbocation reacts with bromide to form the product.

There are two carbon atoms in the product and hence the parent name is ethane
