Question

Give the structures of the following compounds: (a) 2-Butanol (b) 3 -Bromopentane (c) 2-Chloro-2-Propanol (d) 2 -Propanone

Short answer

Question: Draw the structures of the following organic compounds: a) 2-Butanol, b) 3-Bromopentane, c) 2-Chloro-2-propanol, d) 2-Propanone. Answer: a) 2-Butanol: CH3-CH(OH)-CH2-CH3 b) 3-Bromopentane: CH3-CH2-CH(Br)-CH2-CH3 c) 2-Chloro-2-propanol: CH3-C(OH)(Cl)-CH3 d) 2-Propanone: CH3-C(O)-CH3

Step-by-step solution

Identify the functional group and carbon atoms

2-Butanol has an alcohol functional group (-OH). The prefix "but-" indicates that there are 4 carbon atoms.

Determine the position of the functional group

The alcohol group is attached to the second carbon atom due to the "2-" in front of the name.

Draw the structure

The structure of 2-butanol is: CH3-CH(OH)-CH2-CH3 #b)# 3-Bromopentane

Identify the functional group and carbon atoms

3-Bromopentane has a bromine atom as its functional group. The prefix "pent-" tells us there are 5 carbon atoms.

Determine the position of the functional group

The bromine atom is attached to the third carbon atom due to the "3-" in front of the name.

Draw the structure

The structure of 3-bromopentane is: CH3-CH2-CH(Br)-CH2-CH3 #c)# 2-Chloro-2-propanol

Identify the functional group and carbon atoms

2-Chloro-2-propanol has a chlorine atom and an alcohol functional group. The prefix "prop-" indicates there are 3 carbon atoms.

Determine the position of the functional groups

Both the chlorine atom and the alcohol group are attached to the second carbon atom due to the "2-" present twice in the name.

Draw the structure

The structure of 2-chloro-2-propanol is: CH3-C(OH)(Cl)-CH3 #d)# 2-Propanone

Identify the functional group and carbon atoms

2-Propanone has a carbonyl (C=O) functional group. The prefix "prop-" tells us there are 3 carbon atoms.

Determine the position of the functional group

The carbonyl group is attached to the second carbon atom due to the "2-" in front of the name.

Draw the structure

The structure of 2-propanone is: CH3-C(O)-CH3
