विकल्प

• 14 u

• 15 u

• 16 u

• 17 u

Answer 1

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.
