Match List I with List II :

Choose the correct answer from the options given below :

A)Both have the molecular formula $$(C_{3}H_{8}O)$$. In n-propanol, the $$(-OH)$$ group is at position 1, while in isopropanol, it is at position 2.

           Isopropanol

B)These compounds have the same molecular formula $$(C_4H_{10}O)$$ but differ in the distribution of carbon atoms on either side of the ether functional group $$(-O-)$$.

C)Both have the formula $$(C_{3}H_{6}O)$$, but they belong to different functional groups: propanone is a ketone and propanal is an aldehyde.

D)Both are isomers of pentane $$(C_{5}H_{12})$$ but differ in the structure of the carbon skeleton (branched chain vs. more highly branched chain).
