Write the condensed structural formula for each of the following molecules:
a.ethylcyclopropane
b. methylcyclohexane
c. isopropylcyclopentane
I am unable to draw rings on this board.
For cyclopropane, draw a triangle, then attach to one corner a CH3CH2 group.
For methyl cyclohexane, draw a hexagon, then attach to one apex CH3
For ispropylcyclopentane, draw a pentagon, and attach to one apex the ispropyl group (CH3)2C-
To write the condensed structural formula for each of the molecules you've mentioned, we need to understand the structure of these compounds and how they are named.
First, let's understand the basic structure of each molecule:
a. Ethylcyclopropane:
Cyclopropane is a three-membered ring with three carbon atoms. Ethyl means that there is an ethyl group (-CH2CH3) attached to the cyclopropane ring.
b. Methylcyclohexane:
Cyclohexane is a six-membered ring with six carbon atoms. Methyl implies there is a methyl group (-CH3) attached to the cyclohexane ring.
c. Isopropylcyclopentane:
Cyclopentane is a five-membered ring with five carbon atoms. Isopropyl means there is an isopropyl group (-CH(CH3)2) attached to the cyclopentane ring.
Now, let's write the condensed structural formula for each compound:
a. Ethylcyclopropane:
CH3CH2-C(CH3)2
Explanation: The condensed structural formula shows the carbon backbone in a linear fashion. The ethyl group (-CH2CH3) is attached to one of the carbon atoms in the cyclopropane ring. The other two carbon atoms in the cyclopropane ring are represented by the "-C(CH3)2" part, where "(CH3)2" indicates two methyl groups (-CH3).
b. Methylcyclohexane:
CH3-CH2-CH2-CH2-CH2-CH3
Explanation: The condensed structural formula shows each carbon atom in the cyclohexane ring in a linear fashion. The methyl group (-CH3) is attached to one of the carbon atoms in the cyclohexane ring. The other carbon atoms are represented by the "-CH2-" portion.
c. Isopropylcyclopentane:
CH3-CH(CH3)-CH2-CH2-CH2
Explanation: The condensed structural formula shows each carbon atom in the cyclopentane ring in a linear fashion. The isopropyl group (-CH(CH3)2) is attached to one of the carbon atoms in the cyclopentane ring. The other carbon atoms are represented by the "-CH2-" portion.
By understanding the structure of the molecules and the naming conventions, we can determine the condensed structural formula for each compound.
