उत्तर
While going in an increasing order of the length there is a rise in the molecular mass of the members by 14 u.
Explanation:
This question refers to a homologous series in organic chemistry, where each consecutive member in a carbon chain differs by a single methylene group (-CH2-). Because carbon has an atomic mass of 12 u and hydrogen is 1 u, the addition of a -CH2- group increases the total molecular mass by exactly 14 u.
