(a)
Interpretation:
Structural formula for the given compounds has to be written.
Concept Introduction:
Any organic molecule can be named by using certain rules given by IUPAC (International Union for Pure and applied chemistry). IUPAC name consists of three parts in major namely Prefix suffix and root word.
Prefix represents the substituent present in the molecule and its position in the root name.
Suffix denotes the presence of
Root word represents the longest continuous carbon skeleton of the organic molecule.
The structure of a molecule can be drawn by analyzing the presence of prefix, suffix and root word in the given IUPAC name.
Condensed structural formula is representation of the organic compound. In this the lengthy carbon chain is shown only with the carbon atoms (along with the hydrogen) without any bonds. The additional branches are shown with explicit bonds.
If a compound contains only single bonds between the carbon atoms, then it is said to be saturated and if the compound contains double or triple bonds between the carbon atoms present in it, then it is said to be unsaturated.
