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 C n H 2n . 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.

Question

For a CARS experiment on a Raman band 918 cm-1, if omega1= 1280 nm, calculate the omega2 in wavelength (nm) and the CARS output in wavelength (nm).

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .
