Concept Introduction:
A molecule is said to be chiral if it cannot be superimposed on its mirror image and if it does not possess an alternate axis of symmetry.
A carbon atom bonded in a tetrahedral structure to four different substituents in a molecule, it is called as a chiral centre or stereocentre.
If an organic molecule has more than one chiral carbon or chiral centre then the molecule may be achiral or chiral and it is depend upon whether the molecule has element of symmetry or not.
The elements of symmetry are-
- A plane of symmetry
- A centre of symmetry
- n-fold alternating axis of symmetry.
Answer to Problem 15.18P
Explanation of Solution
Since alkanes consist of only carbon and hydrogen, the lowest molecular weight alkane can have four different groups attached to it namely- hydrogen, methyl group, ethyl group, and propyl group.
So the molecule so formed is: 3-Methyl-Hexane.
3-Methyl-Hexane.

Answer to Problem 15.18P
Explanation of Solution
Since alkenes consist of only carbon and hydrogen, with a double bond, the lowest molecular weight alkene can have four different groups attached to it namely- hydrogen, methyl group, vinyl group, and ethyl group.
So the molecule so formed is: 3-Methyl-Pent-1-ene.

- we were assigned to dilute 900ppm in to 18ppm by using only 250ml vol flask. firstly we did calc and convert 900ppm to 0.9 ppm to dilute in 1 liter. to begin the experiment we took 0,225g of kmno4 and dissolved in to 250 vol flask. then further we took 10 ml sample sol and dissolved in to 100 ml vol flask and put it in to a spectrometer and got value of 0.145A . upon further calc we got v2 as 50ml . need to find DF, % error (expval and accptVal), molarity, molality. please write the whole report. thank you The format, tables, introduction, procedure and observation, result, calculations, discussion and conclusionarrow_forwardQ5.
