As one ascends in any homogeneous category, physical properties change in one direction.
Options
Right
Wrong
Advertisements
Solution
The given sentence is right.
Explanation:
This statement is correct because in a homologous series, as the carbon chain gets longer and molecular mass increases, physical properties like melting and boiling points show a regular, steady gradation. Because the change in mass is consistent, these physical properties gradually shift in one specific direction.
