Assign the `R` and `S` configuration to the enantimers of `2`-bromobutane
Strategy: Identify the chiral carbon (stereocentre) and decide the order of priority for the four different ligands using `CIP` rules. Finally orient the molecule and designate the configuraiton.

While assigning R,S configuration the correct order of priority of groups attached to chiral carbon atom is

After completing her studies in product design, Sarita wishes to start her own business to design products to cater to the mobility and communication requirements of persons with special needs. She told her friend that she wanted to focus on supplying high-quality products at affordale prices. The Unique Selling Proposition (U.S.P) of the products would be sensitivity to the challenges and needs of the differently abled people. She wants to employ only differenty abled persons in her factory and sales offices across the country. This decision of Sarita provides the base for interpreting her strategy. This also defines the broad parameters within which the company may recruit the persons. Sarita has also to decide about the exact manner and the chronological order of how the selection of the differently abled applicants will be done. In the above lines, Sarita is discussing about one of the functions of management. This function has several types. Identify and explain the types Sarita is discussing in the above lines

Broadly speaking there are four types of stereisomers namely conformational isomers geometrical isomers, enantiomers and diastereomers.Although conformational isomers , have same configuration geometrical isomers have different atoms attached to each of the doubly bonded carbon atom, and enantiomers are due to chirality in the molecule Enantiomers are also known as optical isomers and diastereomers are those stereoisomers which are not enantiomers.In simple compound, number of stereoisomers.In chiral molecule is given by the reaction 2^n , where n is the number of dissimilar chiral carbon. Observe the following structures and answer the questions given below : How many stereoisomers are possible in pent-3-en-2-ol, CH_3CH=CHCHOHCH_3
