Which of these compounds would you expect to be most soluble in water? ch3ch2ch2f ch3ch2ch2oh ch3ch2ch2ch3 ch3ch2cl description?

Among the given compounds, CH3CH2CH2OH (1-propanol) will have maximum solubility in water. 

Reason: 
Solubility is based on the principle of 'Like dissolves Like'. Hence, water is a polar solvent, hence it will dissolve polar solvent to maximum extent. Among the listed solutes, CH3CH2CH2OH has maximum polarity. 

Further, CH3CH2CH2OH is capable of displaying hydrogen bonding with water, while other compounds will not show hydrogen bonding. With reference to hydrogen bonding, it may be noted that when hydrogen atom is bonded to electronegative elements like O, N and F, it exhibits hydrogen bonding. Due to this, CH3CH2CH2OH will be readily soluble in water. 

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
