|
Members of the series differ by CH3.
|
|
|
Members of the series have the same physical properties.
|
|
|
Members of the series have the same empirical formula.
|
|
|
Members of the series have similar chemical properties.
|
Detailed explanation-1: -They have same general formula and because of a same functional group, they have similar chemical properties but due to varying mass, they have different physical properties.
Detailed explanation-2: -The Chemical properties of the members of a homologous series are the same due to the fact that they all have the same functional groups in them. This series has enabled scientists and engineers to study different organic compounds systematically.
Detailed explanation-3: -They can be represented by a common general formula for alkanes, alkenes, alkynes and other functional groups. As the molecular mass increases in a homologous series, a gradation in physical properties is observed. Therefore, the correct answer is option B.
Detailed explanation-4: -The chemical properties of homologous series are similar because they have the same functional group. However, the physical properties of homologues are different because of increased London dispersion forces. Other molecules besides organic compounds can have homologous series as well.
Detailed explanation-5: -Each member of the series differs from the preceding or succeeding member by a common difference of CH2 and by a molecular mass of 14 amu. ( All members of each homologous series contain same elements and same functional groups. All members of each homologous series have the same general molecular formula. More items
