Question

Write condensed formula and bond line formulae for the following structures.
a.

b.

c.

Answer 1

Hint: The chemical formula in which there is no presence of sigma or pi bonds is called condensed formula. The bond line formula is nothing but we have to represent the total structure of the compound without using the carbon symbol.

Complete Solution :
- In the question it is given that to write the condensed formula and bond line formulae for the given compounds.
- The first given structure is as follows.
a.

- The condensed formula of the structure ‘a’ is $C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{3}}$ .
- The bond line formula of the structure ‘a’ is as follows.

- The name of the structure ‘a’ is butane.

- The second given structure is as follows.
b.

- The condensed formula of the structure ‘b’ is $CNC{{H}_{2}}C{{H}_{2}}CN$ or ${{C}_{4}}{{H}_{4}}{{N}_{2}}$ .
- The bond line formula of the structure ‘b’ is as follows.
- The name of the structure b is butanonitrile.

- The third given structure is as follows.
c.

- The condensed formula of the structure ‘c’ is $C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}COOH$ .
- The bond line formula of the structure ‘c’ is as follows.

- The name of the structure c is butanoic acid.

Note: Condensed formula gives the idea about the number of carbons, number of hydrogens, number of oxygen atoms, and number of nitrogen atoms present in the compound very easily. By using bond line formulas we can easily represent the structures of the organic compounds very easily.
