Question
The correct semi-structural formula for 1,4-dichlorobutan-2-ol is
Solution
The semi-structural formula for 1,4-dichlorobutan-2-ol is:
CH2Cl-CH(OH)-CH2-CH2Cl
Here's the step-by-step explanation:
-
The prefix "butan" in the name indicates that there are four carbon atoms in the longest continuous chain. This forms the base of the molecule.
-
The "1,4-dichloro" part of the name indicates that there are chlorine atoms attached to the first and fourth carbon atoms in the chain.
-
The "2-ol" part of the name indicates that there is a hydroxyl (-OH) group attached to the second carbon atom in the chain.
-
Therefore, starting from the left, the first carbon atom has a chlorine atom attached, the second carbon atom has a hydroxyl group attached, and the fourth carbon atom has a chlorine atom attached. The remaining bonds on the carbon atoms are filled with hydrogen atoms.
-
The semi-structural formula is written as CH2Cl-CH(OH)-CH2-CH2Cl.
