Question

Draw the structural formula of a 2-methylpropane-2-ol molecule.

Answer 1

For this problem, we should know about the general points of the IUPAC naming while naming the compound like the naming of functional groups, alkyl groups, chains, etc so that we can easily draw the structure of the molecule by using its name.

Complete step by step solution:
-In the given question we have to draw the structural formula of the given compound that is a 2-methylpropane-2-ol molecule.
-IUPAC or International Union of Pure and Applied Compound is a method of naming any organic compound.
There are some points to be remembered while names such as:
-If there is one carbon atom in the longest chain then it is named as meth, if two carbon atoms are present then it is named as eth and if three carbon atoms are present then it is named as a prop.
-So, as we can see that the main chain is named as 'prop' so it consists of three carbon atoms with one methyl group that is one carbon atom at 2-carbon.
-Now, the word 'ane' means that there is a single bond present only because for double bond 'ene' is used and for a triple bond, we use 'yne'.
-Now, the last one is the functional group 'ol' which is a suffix for an alcohol group.
-So, the structural formula of the given compound will be:

Note: For other functional groups such as carboxylic acid the suffix -oic acid is used, for aldehyde -al is used, etc. The naming of the functional group is also dependent on the priority order of the functional groups.
