SMiLES....

On the 29th of October,we had learnt about smile notation in class..

SMILES is a specification for unambiguously describing the structure of chemical molecules using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules. it is like simplification of the writen of molecular structures.  

 After that, Mdm linda gave us assignment on smile. We were given 16 stucture of organic molecules and are asked to find their smile notation.. So in order to draw these structure wu must used the chemsketch software. After draw the structure, we can find the smile notation of the structure by clicking 'tools' , 'generate' , 'smile notation'.. 

However. not all these structure are drawn correctly, we need to check if the notation given are correct. these notation can be checked through http://www.daylight.com/daycgi_tutorials/smipractice.cgi. These stucture cannot be simply drawn as the drawing must follow the rules in drawing the organic molecules.

This is the page of the website that mentioned at the above.

 then we checked the answers by writing the notation in the smiles box..

This is the structure and the smiles notation that we had been assingned to do.

 

 

This was the last assignment for this subject. And now we are going to have our final examination for this semester. I hope that all of us can answers the exams smoothly and gets results with flying colours.

Last but not least...

Thank you Mdm Linda for giving us knowledge and helping us in class.

And also not to forget thanks for ur care..
