How many of the following responses are true?
1. A primary alkyl halide will tend to react through an SN2mechanism because there is little hindrance to backside attack anda primary carbocation is not very stable
2. 3-bromo-3-methylpentane will undergo substitution through an SN2mechanism
3. If R-2-bromopentane is allowed to react with OH- the productwill be S-2-pentanol
4. SN1 leads to a racemization of sterechemistry due to thenucleophile attacking from the backside and the leaving groupleaving
5. SN2 leads to a racemization of sterechemistry due to thenucleophile attacking from the backside and the leaving groupleaving
I thought 1, 3, and 4 were right, but my answer was wrong! Pleasehelp!
