Chemistry
(i) Give the IUPAC name of the following organic compounds:
(ii) What is the special feature of the structure of ethyne
(iii) Name the saturated hydrocarbon containing two carbon atoms.
(iv) Give the structural formula of acetic acid.
Answer
(i) The IUPAC names are:
A: Propyne
B: Ethanal
(ii) The special feature of the structure of ethyne is that the two carbon atoms are linked by triple covalent bond formed by sharing three pairs of electrons between the two carbon atoms. The availability of electrons on the triple bond makes ethyne more reactive and hence it undergoes characteristics addition reactions only.
(iii) Ethane [C2H6]
(iv) Structural formula of acetic acid is shown below:
