Rank the following compounds in order of decreasing solubility in water?

Question

2-fluoro butane

2 butanol

2-chloro butane

Answer 1

Like dissolves like. Your dissolving in water so you need polar compounds, or those capable of donating or accepting h-bonds.

2-butanol-- polar, capable of donating h-bonds, and accepting

2-fluoro-- really polar halide. Flourine may accept an h-bond, not sure.

2-chlorobutane-- polar, but not as polar as flourine and no ability to accept/donate h-bonds.

Answer 2

You'll need your solubility chart!

It has all the answers!

Answer 3

idk how am i supposed to kow that ****

Answer 4

2-BUTANOL> 2-FLUORO BUTANE >2-CHLORO BUTANE

ALCOHOLS R MOST SOLUBLE ,IN CASE OF BUTANE -OH GROUP POLARITY.......BUT

HALOALKANES R NOT ABLE TO  FORM HYDROGEN BONDS WITH WATER EVEN THOUGH THEY R POLAR IN NATURE ,

THEY R SOLUBLE IN ORGANIC SOLVENTS

MOREOVER FLUORINE IS MORE POLAR SINCE MORE ELECTRONEGATIVE THAN CHLORINE................................... SO MORE SOLUBLE IN WATER COMPARATIVELY
