Question:medium

In which of the following, the compounds are arranged in the correct order of acidic strength?

Show Hint

Terminal alkynes are acidic ($R-C \equiv C-H$). Internal alkynes ($R-C \equiv C-R$) are not acidic. +I effect decreases acidity: $H-C \equiv C-H>CH_3-C \equiv C-H>CH_3CH_2-C \equiv C-H$.
