Name the following compounds using cis or trans prefixes. a.) HAL CH₂ - CH3 こし 6.) High -e-c -CH₂ CH₂ CH₂ - CH₂ 3.) Draw the condensed formulas for the products in the reactions below. CH-CH2-CH=CH₂ + H₂O b.) Pol H3C-CH-CH=CH-CH₃ + H₂ CH

Answer 1

Part (1):- Condensed structural formula says that all organic structures must be in a single text and all vertical atoms should not be expand. (a) So, the condensed structural formula of the given compound is as below:-

4) (6) Brs.c.c.cH, or Br_ ་ བ Az c-c © fow ure CH₃ -s, ,་ ;,

(b) The condensed structural formula of the given compound is as below:-

(5) CH3 (1) H₂C CH3 CH CH₂ or H₂C & (3) CH (4) (2) & CH₂ CHE CH3 3,4-dimethylpent-1-ene

(c) The condensed structural formula of the given compound is as below:-

CH3 (1) C (6) C (5) CHz or Wue or H2CH C CH3 H. C CH3 (3) 2-methyl-2-hexene

Part (2):- For writing the IUPAC name of any molecule, first we should choose the longest hydrocarbon chain which is called as the parent chain. Numbering of the carbon should start from near to functional group. Now write the substituent group first with their position and then name of the parent chain. (a) So, the complete IUPAC name of the given compound with the numbering of the carbon is as below:-

(1) (4 (5) (3) c— сня о Н;c (2) н н (Cis)-2-pentene

(b) The complete IUPAC name of the given compound with the numbering of the carbon is as below:-

H3C (2) (3) H C= C H2 H2 H H,C-C2-C2-CH (4) (5) (6) (7) (Trans)-2-heptene

(c) The complete IUPAC name of the given compound with the numbering of the carbon is as below:-

(2) (3) (5) (Trans)-4-heptene
