Question

ldentify the compound(s) with asymmetric centers Check all that apply. H3C CH3 CI CI CH2CH3 CI CH(CH32 CH2CH2CH3

Answer 1

Assymentric centres identified by two parameters

1.SP³Hyberidiszed

2.Four different functional groups attached around the carbon .

null

1) 2-methyl Butane

In the case of 2-methyl Butane this holds SP³ but does not have four different functional group around any one of the carbon.

2)2-Butene

In the case of 2-Butene this doe not holds SP³ for carbon 2and 3 because they are SP²and remaing carbons does not have four different functional group around any one of the carbon.

3)1-Dichloropropane

In the case of 1-Dichloropropane this holds SP³ but does not have four different functional group around any one of the carbon.

4)2-methyl-3-chloro hexane.(Assymentric Center)

In the case of 2-methyl-3-chloro hexane this holds SP³ carbon number 3 which has four functional group around it 1 hydrogen ,1chlorine,1 propane,1 methyl ethane , Hence carbon number 3 holds assymentric center

5)Cyclohexane

In the case of Cyclohexane this holds SP³ but does not have four different functional group around any one of the carbon.
