Answer 1

5 main Porsts for an Contains IUPAC name Organic compound ec Su +Secondary Word Prsefix *Word Root This gives nfomation abut the number Carloon atoms present in principal Caroon chain. Woxd Dot far the given Compound is but as its Principal carrbon chain has 4 Carbon atoms. Poimany Prefix Eives information about Cyclic Prinipal Carbon chain. Ib it is Cyclic then Prefx Cyclo Cam be used For open chain Compourd mo Primeay Pretix 1s used Secondary Prefix '- Gives infomation about Substituents Conneeted to Principal Carbon chain Primany Sukbix -- Glve Information about unsaturaten Pincipal Carbon chain, ItSaturatad Primay Subbixane Iunsatraton Double bond -ene Truple bond I-yne Secondary Subtx:-Give Information about functon roup.

CH3)C CH CH(C)CHCl shown belor, Wnutten as The above can be CH3 c-CHCH-CHc Cl The Carbon chain seledael is shoun w dotted Line Longest chain seleead is having 5Carbons. so it is Principal/Pauent Carbon chain, CH CMety)ad -el Cchloro) Substituants are Numbering should be given in a way so that the Sum tha Positions aSubstitaents beecme ass/Louet CH3 3 5 4 5 2 Ct 3 4 2 1 -CH-CHt CH -Ct CH-CC CtB 2+2+4+5= 13 1+2.+4t4 11 Two twod SubsHtuens Two- Substituents Substituons TUD-C Subctitaents Lowest sum df the PosiCoos is obseruved when given is numbering night to lutis setected igeut tubt. So.

CH3 2 41 _3 -CH2CH-CHY Сs word oot: 5-Carloon chain. So Pent is woodat JosubbixParent chain is saturated Carbon Parent chain is, o-Sukbix is ane chain. So 2-Prefix Two -CH Substituents are at C-4 and two-cl substituents at C-1 & C-2 aYe Present While writtng tha name &the Substituents chloro Should be witen fixst than mety, As chloro Comes first în alphabeticaf onder 2-Prefix 1,2-dichloro-4,4- dimethyf 1,2-dichloro4,4-dimethylPentane IUPAC name
