Draw the electron dot structures for
(a) ethanoic acid
(b) propanone
(c) H2S
(d) F2.
The electron dot structure of ethanoic acid, H2S, propanone, and F2 are given below:
[Extra information: A homologous series is a group of organic compounds having similar structures and similar chemical properties in which the successive compounds differ by -CH2 group. The molecular formula of the 2nd and the 3rd member of the homologous series whose first member is methane are: Ethane (C2H6) and Propane (C3H8).
Example: All the alkanes have similar structures with single covalent bonds and show similar chemical properties, so they can be grouped together in the form of a homologous series.
The hydrocarbons which are members of the same homologous series are:
Alkanes: C3H8, C4H10
Alkenes: C5H10, C8H16
Alkynes: C6H10, C7H12
A covalent bond/ molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. The electron pairs are known as shared pairs or bonding pairs, when they share electrons and hence, is known as covalent bonding.
Example: Covalent bonding between hydrogen atoms.]
