A	B	C	D
\[\begin{array}{cc} \phantom{.}\ce{H}\phantom{......}\ce{H}\\ \phantom{.}\backslash\phantom{.....}/\\ \ce{C = C}\\ /\phantom{.....}\backslash\\ \ce{H}\phantom{......}\ce{H} \end{array}\]	\[\begin{array}{cc} \phantom{........}\ce{H}\phantom{.....}\ce{O}\\ \phantom{.......}|\phantom{....}//\\ \ce{H - C - C}\\ \phantom{......}|\phantom{.....}\backslash\\ \phantom{...........}\ce{H}\phantom{.....}\ce{O - H} \end{array}\]	\[\begin{array}{cc} \ce{H}\phantom{....}\ce{H}\\ |\phantom{.....}|\\ \ce{H - C - C - H}\\ |\phantom{.....}|\\ \ce{H}\phantom{....}\ce{H} \end{array}\]	\[\begin{array}{cc} \ce{H}\phantom{...}\ce{H}\phantom{....}\\ |\phantom{....}|\phantom{....}\\ \ce{H - C - C - O - H}\\ |\phantom{....}|\phantom{.....}\\ \ce{H}\phantom{....}\ce{H}\phantom{.....} \end{array}\]

Options

• A and B are unsaturated hydrocarbons

• C and D are saturated hydrocarbons

• Addition of hydrogen in presence of catalyst changes A to C

• Addition of potassium permanganate changes B to D

Answer 1
