All members of a homogeneous series can be represented by the same general formula. Choose the wrong formula from the following. Alkane – CnH2n + 2 Alkyne – CnH2n + 1 Alkine – CnH2n – 2 A. Alkane – CnH2n + 2 B. Alkane – CnH2n + 2 and Alkine – CnH2n – 2 C. Alkine – CnH2n – 2 D. Alkyne – CnH2n + 1 / Alkine – CnH2n + 1

The correct answer is D. Alkyne – CnH2n + 1 / Alkine – CnH2n + 1.

A homogeneous series is a group of compounds that have the same general formula and similar chemical properties. The general formula for alkanes is CnH2n+2, for alkenes is CnH2n, and for alkynes is CnH2n-2.

In option D, the general formula for alkynes is given as CnH2n + 1 / CnH2n + 1. This is not possible, as the general formula for alkynes is CnH2n-2. Therefore, option D is the wrong answer.

The other options are all correct. Option A gives the general formula for alkanes, option B gives the general formula for alkanes and alkenes, and option C gives the general formula for alkynes.

I hope this helps!
