Question
Can someone please explain this...I thought it was saying you could have either the s chiral center or the R ....
But It is displayed as if both are made.. I don't understand. CHANISM FOR THE REA AMECHANISM F Stereochemistry of an SN1Reaction CH2CH2CH3 acetone H (cosolvent) H CH Br : HÖ Step 1 CHCH,CH3 Br : H,C Departure of the leaving group (assisted by hydrogen bonding with water) leads to the carbocation. Step 2 H,CH2C A racemic mixture of protonated alcohols results H,CH,C H.C HjCH,C//CH,CH,CH, Attack at either face: The carbocation is an achiral intermediate. Because both faces of the carbocation are the same, the nucleophile can bond with either face to form a mixture of stereoisomers. 0 nechanim continues on the next page)
Explanation / Answer
It doesn't mean that two molecules of 3-methyl-3-hexanol are produced.
But it mean that a racemic mixture of enantiomers are produced.
For example, 60% S enamtiomer + 40% R enantiomer is produced
It implies only one molecule of racemic mixture of 3-methyl-3-hexanol is produced.
I hope you understood.
Still if you have doubts, feel free to comment
